101 Questions and Answers about Bitcoin

Bitcoin Basics

What exactly is Bitcoin?

Bitcoin is a decentralized worldwide monetary system that consists of an electronic payment network as well as the digital money that is utilized on it. Payment networks and currencies are typically kept distinct in today’s world; for example, dollars, euros, and yen are currencies, while credit cards are payment networks that make it easier to spend those currencies. Bitcoin, on the other hand, combines the network and the money into a single system. The system is totally based on the Internet, and it fully exploits its strength and worldwide reach.

Who is the inventor of Bitcoin?
Bitcoin was created by Satoshi Nakamoto. “Satoshi Nakamoto” is most likely a fictitious name for the person (or people) who created it. The real identity of Nakamoto is unknown, and he (or she, or the group) hasn’t been active in Bitcoin since 2010. Some people are concerned about Bitcoin’s enigmatic beginnings, but as we’ll see, it was built specifically to avoid being controlled or managed by a single person or organisation.

When did Bitcoin get its start?
In November 2008, Satoshi published a white paper on the internet that was the first to propose the concept of Bitcoin. Satoshi Nakamoto released the original Bitcoin code in January 2009, and the network was launched by “mining” the first bitcoins.

When did the first “real-world” Bitcoin transaction occur?
Bitcoin was first used in a “real-world” transaction (the purchase of something of known value) on May 22, 2010. On that day, a programmer named Laszlo Hanyecz paid 10,000 bitcoins to a fellow Bitcoin user for two Papa John’s pizzas. Many Bitcoin enthusiasts now celebrate May 22 as “Bitcoin Pizza Day.” Hanyecz’s pizza order inaugurated the use of Bitcoin in everyday transactions.

Why was Bitcoin created?
As both an electronic payment system and a currency, Bitcoin was created to resolve problems of both a technological and an economic nature. Technologically, Bitcoin addresses the inefficiencies of traditional payment systems, such as expensive transaction fees, widespread fraud, and slow money transfers. Economically, Bitcoin addresses the requirement of a trusted third party for financial transactions as well as government control of the money supply.

Why is Bitcoin called a “cryptocurrency?”
Cryptocurrency is a generic term that describes a currency based on cryptography (the science of encryption). Most currencies today are backed by governments, whereas Bitcoin is backed by mathematical protocols.

What is an “alt-coin?”
Since the creation of Bitcoin, many other people and groups have created electronic currencies and payment networks similar to Bitcoin. These alternative systems are generically called “alt-coins” and are also cryptocurrencies. Most alt-coins are simply variations of Bitcoin itself, with minor changes in how they work. These alt-coins will not be covered in this book, but many of the concepts behind them are the same as those behind Bitcoin.

Bitcoin seems confusing – is it just for tech geeks?
Bitcoin can seem confusing at first, for it works in a way different than most currencies and payments systems. The technology and economics behind it can be daunting. However, the same could be said for other popular technologies, such as email and social media. Very few people could explain the technology behind how email works, but just about everyone knows how to use it. Bitcoin may not be as user-friendly as email yet, but it is quickly developing such that understanding what’s happening “behind the scenes” won’t be necessary for using it.
The purpose of this book is to give a basic understanding of Bitcoin for non-technical people, so hopefully after you have completed it, it won’t seem so confusing!

Bitcoin as a Payment Network

What is Bitcoin’s function as a payment network?

The Bitcoin network, also known as “Blockchain,” is a sophisticated electronic payment network that allows users to trade bitcoin, the money (notice the lowercase “b” to separate the currency from the Bitcoin network as a whole). The Blockchain is an online database that records all Bitcoin network transactions and prohibits anyone from illegally sending or receiving bitcoins. The Blockchain is innovative and unique in that it allows users to send money electronically without the need of a trusted third party such as a bank or credit card provider. Although various digital currencies or ideas for digital currencies have existed in the past, Satoshi’s development of the Blockchain provides a real mechanism of trading digital currency safely and effectively.

What is the significance of the term “blockchain”?
Because all transactions are gathered in “blocks” that are “chained” together all the way back to the first block ever produced, the Bitcoin payment network is known as the Blockchain. No one can go back in time and fake prior transactions since all transactions in Bitcoin history are connected, and these transactions are saved on computers all around the world.
What is the Blockchain and how does it work?
The transaction is sent to the Bitcoin network every time someone sends bitcoins to another user. The new transaction is included and so recorded on the Bitcoin network when a new block (group of transactions) is added to the Blockchain. If Alice transmits 3 bitcoins to Bob at 10:59 a.m. on September 9, 2015, their transaction is permanently recorded on the Blockchain, informing the whole network that Alice no longer has possession of those bitcoins and that Bob now does.

What is the location of the Blockchain?
Every computer in the world that is running a complete “node” on the Bitcoin network has a copy of the Blockchain. A Bitcoin node can be run by anybody. This is what makes Bitcoin decentralized, as it prohibits any single person or group from seizing control of the network. There is no centralized command center where an attack may be launched.

Is the Blockchain a safe system?
The Blockchain’s architecture makes it very secure.
Bitcoin “mining” is how blocks are added to the Blockchain. Each block contains several transactions and is linked to the preceding blocks in a chain. The longer a block has been on the Blockchain, the more secure it is, according to the procedure. This is because each new block adds to the validity of the previous blocks.
Consider putting 1,000-pound weights on top of one another. Lifting the top weight off the stack would be quite tough. But what if there were 500 weights in the stack, and you only had to lift the top 300? The Blockchain is built in such a way that the deeper you go into it, the more secure it becomes.

Furthermore, Bitcoin employs “public-key cryptography” to ensure that transactions are not tampered with. This is a sophisticated encryption technology that prohibits someone from taking control of another’s bitcoins or posing as someone they are not. Furthermore, because the Blockchain records all prior transactions, no one can “double-spend.”

What does “double-spending” bitcoins imply?
Sending the same bitcoins to two different receivers is known as “double-spending.” The Blockchain’s validation procedure prevents this from happening. For example, if Alice gives three bitcoins to Bob and then attempts to send the same three bitcoins to Carol 20 minutes later, the Blockchain will recognize the first transaction but reject the second, since Alice no longer has possession of the bitcoins.

What is a Bitcoin node, and how does it work?
A “node” is essentially a machine that runs the Bitcoin software and sends transactions across the Bitcoin network. Only genuine transactions — those that follow the Bitcoin protocol – are sent by nodes. Nodes also keep a local copy of the Blockchain and sync it with the rest of the network on a regular basis. The Bitcoin network is very resistant to assaults and efforts to shut it down since each node stores the whole Blockchain. To keep the network alive, all that is required is one working node. On September 1, 2015, the Bitcoin network has over 6,000 nodes operational throughout the world.
It’s worth noting that the Bitcoin network is non-hierarchical, which means that no node is more essential than another. Any node in the network can propagate transactions, and each node takes up and propagates transactions from other nodes.
What is the definition of a Bitcoin confirmation?
Apart from conventional nodes, specialized nodes known as “miners” run on powerful computers and append groups of transactions to network “blocks.” This is known as a Bitcoin “confirmation.”
A miner node will add a transaction to a future block when Bitcoin nodes have validated it and forwarded it to the Bitcoin network, thereby validating the transaction. A confirmation indicates that the transaction has been completed.

The Bitcoin network has accepted you.
A transaction with “many confirmations” is a term used frequently in Bitcoin. This signifies that the transaction was included to a block (1 confirmation) and that following that block, more blocks were added to the Blockchain. Each new brick, in a way, reinforces the previous ones. Assume Alice’s transaction has been included to block #201. Her transaction will have two confirmations when block #202 is added; it will have three confirmations when block #203 is added, and so on. The less probable a transaction is to be fraudulent, the more confirmations it gets, because each extra confirmation better confirms the transaction. Even a transaction with only one confirmation is unlikely to be fraudulent, because adding each block necessitates a complex technique of transaction validation.

How long does it take for a transaction to be confirmed?
In most cases, a Bitcoin transaction is instantaneous, similar to sending an email. Most merchants, however, wait until the transaction is verified on the Bitcoin Network before accepting it to avoid the potential of a double-spend. Each confirmation might take up to ten minutes on average. A merchant may accept a transaction without any confirmations for modest transactions, such as a cup of coffee, but most experts require 4-6 confirmations for bigger purchases, which might take up to an hour.
An hour seems excessively long for a transaction to be validated — how can this be practical?
There are two things to consider: First, a transaction is entirely verified after it has gotten six confirmations. A regular credit card transaction, on the other hand, can take up to 90 days to settle — and chargebacks are still conceivable during this period.
Second, as previously said, smaller transactions may be completed with far fewer confirmations (or even no confirmations). Entrepreneurs are also developing new techniques to validate transactions more rapidly in a way that is acceptable to both merchants and customers.

Are there any additional applications for Blockchain?
Absolutely. Experts believe that a technology like Blockchain might have a wide range of applications. A decentralized online ledger with mathematically guaranteed security might be used to validate contracts, monitor stock ownership, record any form of financial transaction, and a variety of other things.

Bitcoin as Currency

What is Bitcoin’s function as a currency?
Anything that is utilized as a means of trade is referred to as a currency. Rather than a barter system in which I trade what I have for what you have, currency allows us to buy and sell items in a standard unit of measurement: $3 for a gallon of milk, $10 for a pound of steak, and so on. Bitcoin has a built-in currency called “bitcoins.” People may own, spend, and receive bitcoins just like any other currency. Unlike other currencies, however, bitcoins are the first commonly used entirely digital money.

Do bitcoins come in multiple denominations?
There are numerous denominations of bitcoins, just as there are different denominations of government-issued currencies (such as the dollar, quarter, dime, nickel, and penny). The “bitcoin,” which (obviously) equals 1 bitcoin, is the most common denomination. Each bitcoin may now be divided to eight decimal places, resulting in 0.00000001 bitcoins. The lowest bitcoin denomination, one hundred millionth bitcoins, is known as a “satoshi,” after Bitcoin’s founder Satoshi Nakamoto. One bitcoin is made up of one hundred million satoshis. Also known as a “bit,” 0.000001 (one millionth) bitcoins are sometimes referred to as such. A bitcoin is made up of a million bits.
Although there has been some debate about naming other bitcoin denominations, the bitcoin, bit, and satoshi are currently the three most widely accepted. Most Bitcoin users feel that other denominational quantities will need to be identified at some point in the future in order to make Bitcoin more user-friendly. “I’m sending you 200 bits,” rather than “I’m sending you 0.0002 of a bitcoin,” is a lot easier to say.

What is the process of creating bitcoins?
A certain amount of bitcoins are added to the Bitcoin network every 10 minutes or so. This is accomplished through a procedure known as “mining.” Of course, we don’t mean that actual coins are generated when we say bitcoins are “made.” What this means is that the Bitcoin payment network now has more bitcoins available.

What is the total number of bitcoins in circulation?
Every ten minutes, the number of bitcoins in circulation on the Bitcoin network is increased. The Bitcoin network, on the other hand, is set up to contribute a decreasing amount of bitcoins over time. By the year 2140, there will be a total of 21 million bitcoins in circulation, and the process of adding new bitcoins will be completed. There were roughly 14,560,000 bitcoins on September 1, 2015.

What is the Bitcoin symbol?
Bitcoin, like every other money, is identified by a symbol. Bitcoin’s most often used symbol is BTC (an upper-case B with two vertical lines through it). Because many devices are unable to display this sign, several symbols have been offered, but none have been widely embraced by Bitcoin users. It is also common to use the shorthand “BTC” to refer to a bitcoin, thus if someone possesses four bitcoins, they may write “4 BTC” or “4 BTC.”

Ownership of Bitcoin Network

What is the ownership of the Bitcoin network?
The Bitcoin network is not owned by any single person or entity. Bitcoin, like the Internet on which it is based, is decentralized, meaning that no single body has control over how it functions or how bitcoins are allocated and spent. This is unusual in today’s world of currencies, which are all established and regulated by governments. Bitcoin’s operation and development are based on consensus, which means that its users decide how it will work and function.

So, if Bitcoin is decentralized, who or what controls it?
Bitcoin is governed by a set of protocols that regulate the network’s whole operation (much like the Internet is controlled by specific protocols). These protocols define how bitcoins are added to the network, how bitcoins are exchanged from one user to another, and all other regulations that make the Bitcoin network function.

Is there somebody in charge of the Bitcoin protocols?
Consensus is in charge of the Bitcoin protocols. To be accepted into the Bitcoin network, each proposed modification must have the backing of the majority of Bitcoin users.
Let’s imagine someone suggests that instead of 21 million bitcoins, the network creates 100 million bitcoins. If that individual made that update to his version of the Bitcoin software, it would have no effect on the rest of the network unless others followed suit.
The owner of 100 million bitcoins, on the other hand, has no motivation to make this adjustment if there is no agreement in favor of it. Why? If he modifies his version, he will form a new network, known as a “fork.” This split would break compatibility with the main Bitcoin network, and the fork’s money would become worthless since no one would use it.
When Bitcoin protocols are changed, it is done by a group of core developers who manage the Bitcoin program. They make minor adjustments, such as bug fixes, with little major discussion. However, every now and then, a substantial change is proposed, and Bitcoin users are divided on the merits of the change. The process of reaching an agreement in these situations may be nasty and chaotic, with intense disputes between the two sides of the problem. This may appear inefficient, but it is actually workplace democracy. Only those changes will be applied that are agreeable to the majority of Bitcoin users. By choosing the version of the program they use, users “vote” for what they desire. When the majority of users pick a version that includes the modification, the change is implemented.

Can these open-source, decentralized protocols truly work?
This decentralization is frightening to some individuals. We think that in order to avoid anarchy and turmoil in a project, there must be only one “voice.” In reality, however, this is not the case. Consider the use of words. Despite the fact that no one “invented” English and no one is in charge of keeping it up to date, we clearly have the ability to communicate with one another. This has happened as a result of millions of individuals agreeing on how we communicate. The language has been maintained by no organized authority.
Bitcoin decentralization works because all Bitcoin network users are motivated to reach an agreement. If there is no agreement, Bitcoin will disintegrate and become worthless to its users. As a result, Bitcoin users work to guarantee that a consensus is formed.
Technological Advantages of Bitcoin

What are Bitcoin’s technological advantages?
Bitcoin is a cutting-edge payment network that outperforms traditional payment networks developed prior to the Internet. Bitcoin has two major advantages: (1) it considerably minimizes the risk of identity theft and credit card fraud, and (2) it greatly enhances the convenience of making payments. Bitcoin is a decentralized payment network built from the ground up for the Internet Age.

What is Bitcoin’s approach to credit card fraud?
Our existing credit card payment methods rely on technology developed before to the Internet’s inception and never designed for usage online. Although many consumers use their credit cards online without incident, this appears to be a false sense of security that is bolstered by billions of dollars in financial institution assistance – monies that are eventually charged to the customer (i.e., you and me).

When it comes to credit card fraud, how does the customer get charged?
When a client’s credit card is used illegally, it is now normal policy that the consumer is not liable. So, if someone uses a stolen credit card to buy $500 worth of goods from an online merchant, the real owner of that credit card is not responsible for the $500. Nonetheless, $500 was spent – so who is responsible for it? The bank, in most situations, treats it as a cost of doing business. However, fraudulent charges amount to billions of dollars (one research projected $190 billion in the United States alone in 2009), and banks do not fully absorb such losses. Instead, they compensate for them by charging shops credit card fees. When you spend $100 at a retailer using your credit card, the store usually only gets $97-98, and the bank gets the difference. This does not appear to be an issue for the client because the shop bears the expense. Retailers, on the other hand, take these costs into account when setting their pricing; they must mark up their prices to meet the credit card fees they must pay. And who foots the bill? The customer. As a result, fraud-related costs totalling billions of dollars are added to the cost of goods merely because the payment system is ineffective at preventing fraud.

Why is the payment mechanism for credit cards so vulnerable to fraud?
One of the most serious issues in our existing credit card payment system is that when a customer buys anything, she gives up access to her whole account. To purchase a $10 book online, you provide your name, address, and all credit card information (number, expiration date, and card security code). To put it another way, you’ve exposed everything a hostile individual needs to have access to your whole bank account’s funds. Despite the fact that this is now the standard, it is extremely insecure, as seen by the numerous credit card breaches that occur in both online and brick-and-mortar establishments.

What distinguishes Bitcoin from this credit card payment system?
Bitcoin has a fundamentally new payment paradigm, one that is more akin to cash. When you send bitcoins to someone else, you only give him those precise bitcoins. He can’t get any more of your bitcoins since he doesn’t have a mechanism to get them. If your name or contact information isn’t necessary for the transaction, you don’t have to provide it to him. It’s the same as handing over a $20 dollar to the cashier, but it’s all done electronically. Bitcoin, on the other hand, is similar to cash in that it is non-reversible: if you give bitcoins to someone else, you won’t be able to retrieve them back unless the other person decides to pay them to you.

What is Bitcoin’s approach to payment convenience?
Bitcoins can be transferred instantly and securely across the Bitcoin network since the system is entirely based on mathematical rules and robust encryption. The procedure does not require human interaction and costs about the same as sending an email — a pittance.
Credit card transactions might take weeks to settle, even if we don’t recognize it as customers. Furthermore, transmitting any substantial sum of money (say, $10,000) online is a costly and time-consuming operation. Bitcoin can transmit any amount of money in an instant, and it generally costs only a few cents.

Economic Advantages of Bitcoin

What are Bitcoin’s economic advantages?
Bitcoin’s economic model differs greatly from that of government-issued currencies such as the US dollar or the euro. As a result, it offers several benefits over other currencies, the most important of which are that it does not require the use of a trusted third party to confirm transactions, it is not susceptible to government control of the money supply, and it has really worldwide reach.

What does it indicate when a transaction is validated by a “trusted third party”?
Consider a standard financial transaction. You place an item on Amazon and provide your credit card information during the checkout process. Despite the fact that this transaction is only between you and Amazon, a third party is involved. For example, how can Amazon and other sellers know that your credit card is legitimate and that you have sufficient cash to cover the transaction price? They don’t work on their own. Financial institutions (banks and credit card firms) are trusted to verify this.
Even when you pay with cash, there is a third party involved: the government that backs the currency. For the merchant, the amount reflected on the note – $1, $5, $20 – represents the true value of that piece of paper. However, if the government decides to expand the money supply, that piece of paper loses its purchasing power.

What’s wrong with having to entrust financial transactions to a third party?
Having a third party behind a financial transaction may often be beneficial. But this isn’t always the case, because when you have to rely on a third party, you don’t have complete control over your finances and no true independence. For example, many government officials and economists throughout the world are actively advocating for the abolition of currency, or at the very least a significant reduction in its use. Many businesses will not take cash for significant transactions due to restrictions imposed by their financial institutions, and there are already severe limits on how much cash a person may withdraw from her own bank account. Furthermore, in nations where governments are oppressive, the “trusted” third party is frequently under government control (or is the government itself), and any transactions that are not sanctioned by that government are refused – and maybe even grounds for incarceration.

How can Bitcoin eliminate the requirement for a third-party trust?
When a transaction takes place on the Bitcoin network, the transaction is validated by the network using mathematical computations and encryption. The transaction does not require the involvement of an organization or government for approval.

Why is it a challenge for the government to regulate the quantity of money?
Because the government controls the supply of money, the value of that money is vulnerable to the whims and wishes of government officials, who are usually only concerned with short-term issues. As a result, the value of all government-controlled currencies has depreciated over time. The value of the US dollar has plummeted by nearly 96 percent since the Federal Reserve, the country’s central bank, was established in 1913. To put it another way, a dollar today is only worth around 4/100th of what it was in 1913. Over the last 100 years, this has been a steady reduction – a dollar today can only purchase around 35/100ths of what it could 35 years ago. Take a look at the graph below, which illustrates how many loaves of bread you could buy with $10 during the last 100 years:

Since 1915, the dollar has bought fewer loaves of bread each year.
Inflation, or a rise in the quantity of money, is the cause of the dollar’s sharply declining value.
In principle, salaries will rise as well (though rising wages generally lag behind rising costs of commodities), but the dollar’s declining value is an issue since it means that the money you earn today – your earnings – will be able to purchase less the longer you keep it. As a result, a dollar earned today is worth 98 cents the next year. This motivates you to spend your money, even if you don’t want to, because money loses its worth as time passes. It also makes it difficult to save for the long term – instance, for retirement – since your money loses purchasing power with each passing year.

Isn’t it the job of the government to issue money?
Not at all. Many people believe that money and the government are inextricably intertwined, but this is not the case. Some believe that it would be better if the government didn’t deal with money at all, because it wouldn’t be able to print more if it couldn’t generate “enough” money through taxes. In the history of government-issued money, one constant has been that it has always been worthless. Always.
Governments, on the other hand, did not create money.
Money did not start with the government, contrary to common perception. Certain commodities were considered as having ideal features for a means of trade as they evolved from barter: easy to divide, transportable, durable, and fungible (one unit of the currency is worth the same as any other unit). Governments began to develop currencies using commodities (typically gold or silver) when they became acceptable for exchange. It wasn’t a monarch who declared, “Let this be money!” — it was the collective decisions of countless individuals in the actual world (the “market”) that determined what produced the most money.
Why does an increase in money supply cause the value of a dollar to fall (increasing prices)?
Consider the following situation: Alice and Bob each have $100 and are interested in the new bike Carol is selling. Alice is prepared to pay $90, but Bob is willing to pay the full $100. In such situation, Carol will sell it to Bob, presuming she is mainly concerned with the amount of money she would receive. What if both Alice and Bob received a $100 present from their grandmothers? Now Alice could return and offer more than $100, knowing she still has some cash on hand. Bob, on the other hand, is more concerned with the bike than with the money, and he may now be ready to pay up to $200. In either instance, the increased money supply resulted in a higher bike purchase price. Of course, in a complex economic system like the United States, this process is a little more convoluted, but the essential logic remains the same: increasing the money supply leads to higher prices.

Why is it that growing prices are a negative thing?
Because of rising costs, the money we make can no longer buy as much as it could previously. This penalizes us for saving since the value of money we hold falls with time. Saving money for the future is not something that should be penalized in a strong economy, according to common sense.

What is Bitcoin’s strategy for dealing with inflation and rising prices?
There will never be more than 21 million bitcoins in the Bitcoin network at any given moment. A government or company cannot modify that number; the only way it can be modified is if the Bitcoin community as a whole comes together and agrees to do so (something very unlikely to happen). With a fixed money supply, increasing the price of commodities becomes much more difficult; in fact, the same items will frequently cost less over time. This, according to Bitcoin’s creator and supporters, is beneficial to everyone.

Willn’t a money that appreciates in value deter people from spending it?
Some believe that consumers will be unwilling to use a money that appreciates in value over time if they hold it. If $100 now can purchase a desk, but $100 in two years can buy two desks, individuals are apparently more likely to save their money for a better deal in the future. However, consider the electronics sector as an illustration of what does not occur.
Electronic gadgets like computers, tablets, and smartphones have become more powerful while simultaneously becoming less expensive over time. In fact, if the money itself increased in value, this is what would happen in all businesses (i.e., prices would go down). Despite this, consumers continue to buy electronic equipment, and decreased costs do not deter them. There are some expenditures that everyone must make (food, housing, clothing, etc. ), but having a growing (or stable) value of one’s currency allows a person to spend or invest without fear of her funds depreciating in value.

Is Bitcoin restricted to a single country or a few countries?
Bitcoin, unlike current government-issued currencies, has a genuinely global reach. It is not controlled by any government and, because it is not linked to any country’s currency, it may be used anywhere on the planet. This implies money may be moved across nations without the requirement for currency conversion or high fees. In Austria, a bitcoin is valued the same as it is in Zimbabwe.

Is there any additional benefit to Bitcoin from a financial standpoint?
Bitcoin is not easily manipulated by global forces since it is decentralized and independent of any government or organization. Because the Bitcoin protocol controls the quantity of bitcoins, there is no possibility for extra bitcoins to be issued in the event of a crisis, as is the case with government-controlled currency. When a country wants to go to war with another country but can’t fund it through taxes, it produces new money, according to history. When it can’t garner support for raising taxes to implement a social initiative, it produces fresh money. Even democratic governments can engage in behavior that is against the will of the people and is paid for by the people when they control the money supply.

Using Bitcoin

What are the benefits of using Bitcoin?
Bitcoin outperforms traditional currencies and payment networks in many ways. It may be tough to get started with Bitcoin, but once you do, you’ll see how much easier, less expensive, and more handy it is to use than credit cards or even cash. Bitcoin is humorously referred to as “Internet Magic Money” because it appears to function in a way that our outmoded payment mechanisms do not. Bitcoin provides a genuinely integrated electronic payment system for a society that conducts the majority of its business online.

How can I keep my bitcoins safe?
Bitcoins are kept in a “Bitcoin wallet,” which is software that runs on a computer or other electronic device (phone, tablet, etc.). A password that you establish when you initially install the wallet protects your bitcoins. This password must be kept secure and secret since it grants full access to the wallet and all bitcoins it contains.

What are Bitcoin wallets and how do they work?
Bitcoin wallets maintain track of Blockchain transactions, enable you to transmit bitcoins that you own, and allow you to receive bitcoins from other people. Some wallets are also nodes, storing a full copy of the Blockchain on the device, while many wallets, like as smartphone wallets, are not, merely keeping track of the information required to access the Blockchain.
A person does not “own” bitcoins; rather, he manages them. Without getting too technical, a wallet really keeps your “private key,” which allows you access to specific bitcoins (or fractions of a bitcoin) that you own. When you pay for a product or service, you hand over control of some bitcoins to the other party.

What is the definition of a private key?
A private key is what allows you to control particular bitcoins while also preventing others from doing so. It’s termed a “key” because it allows you to utilize bitcoins. A private key is nothing more than a lengthy string of alphanumeric characters. However, in most wallets, only the wallet password has to be remembered, not the private key. The private key is stored in an encrypted format in the wallet and is used by individuals who have access to the wallet (i.e., those with the wallet password). On the Bitcoin network, a private key is always associated with a “public address.”

What is the significance of private keys?
When it comes to keeping bitcoins, the most essential thing to remember is that anyone who has access to your private keys has access to your bitcoins! Handing someone your private key is the same as giving them the key to your house: they have total power over whatever the key unlocks.

What is the definition of a public address?
To receive bitcoins, you’ll need a public address. It’s similar to having an email address (e.g., me@mail.com) that others require to send you emails. A public address, like a private key, is a lengthy alphanumeric string like “1K65tkPwZD67WdC1xUqi5aJkeoyS6oiJdK.” While your private key remains private, your public key is visible to anybody (and must be visible to others in order for them to pay you bitcoins!).

What is the relationship between a private key and a public address?
Through a process known as “public-key cryptography,” private keys are connected to public addresses. These strings are constructed using difficult mathematics in such a way that someone may easily confirm that a public address is connected to a private key if they know the value of the private key, but knowing the value of the private key even if they know the public address is nearly impossible. Consider the following equation as an example:

20.832 = 415×3 – 391×2 + 132x

It will be tough for you to answer within a few seconds if I ask you what “x” is. However, if I tell you that x=4, you will be able to confirm it in a matter of seconds. Public-key cryptography employs complex mathematics to generate a problem that can only be solved in one way by even the most powerful computers. This allows someone with a private key to quickly access the bitcoins connected with the matching public address, but it is difficult for someone who only knows the public address to do so. Note that the computations required to connect private keys and public addresses are performed behind the scenes, and the average user is not required to comprehend or even be aware of what is going on.

What is the best place to buy a Bitcoin wallet?
Bitcoin wallets may be obtained via www.bitcoin.org, and smartphone wallets can be downloaded through the Apple and Android stores. There are downloaded wallets that you install on your device, as well as online wallets that keep all of your wallet’s information on a remote server. Hardware wallets, which are tiny devices that connect to your computer and are devoted to securely storing, spending, and receiving bitcoins, are another alternative.

What if I forget the password to my Bitcoin wallet?
If you forget the password to a Bitcoin wallet, you lose access to that wallet and all of the bitcoins it holds. Without your password, there is no way to recover the bitcoins from that wallet. This is both a benefit and a drawback: it ensures that no one can access your wallet without your password, but it also means that you can’t access it without it.

Is it possible to back up my bitcoins?
Yes, you can (and should) back up your Bitcoin wallet. If your computer breaks and you lose everything on it, including your Bitcoin wallet, you can recover it using a backup and your password. Backups are handled differently by each wallet software, but generally speaking, backing up your wallet requires moving a specific file to another device.

How can I keep my bitcoins safe?
The first step in keeping your bitcoins safe is to create a strong, secret password for your Bitcoin wallet. However, because your wallet is stored on your computer, it is conceivable that someone may take your bitcoins if your computer is compromised (for example, if a hacker installs a program to record you when you type your password). As a result, most experts advise keeping significant amounts of bitcoins in “paper wallets.”

What is the purpose of a paper wallet?
We saw how private keys and public addresses are used to control bitcoins. These are essentially lengthy sequences of letters and numbers that may be written down on a sheet of paper and kept in a secure location. These private keys/public addresses cannot be hacked and your bitcoins stolen since they are not kept on a computer. A “paper wallet” is a method of storing bitcoins in this manner. “Cold storage” is another word for a paper wallet. When you wish to access your cold storage bitcoins, most Bitcoin wallets provide an import option that allows you to bring them into your wallet.

How can I give bitcoins to people?
Sending bitcoins is, in theory, as simple as sending an email. You enter two pieces of information into your wallet software: the public address of the individual to whom you want to transfer bitcoins and the amount to send. Then press the “Send!” button.

Is sending bitcoins really that simple?
No, not at all. In fact, transmitting bitcoins is similar to sending email in the early 1990s – it’s inconvenient and complex. Despite the fact that great progress has been made in this area in recent years, transmitting bitcoins can still be difficult for the inexperienced. The most inconvenient aspect of the procedure is the public speeches. They’re not simple to memorize or enter into wallets for transmitting since they look like this: “1K65tkPwZD67WdC1xUqi5aJkeoyS6oiJdK.”

Is it possible to make the mailing procedure simpler?
Many businesses are attempting to make it easier to transmit bitcoins. The usage of “QR Codes” is now the most frequent method of simplifying these addresses. These are some examples of photos that look like this:

A smartphone may be used to scan a QR Code, which instantly inputs the public address. Many QR Codes additionally feature the amount to transmit and a label indicating the payment’s purpose.
Going forward, this is one of the most important issues that has to be addressed before we can anticipate wider Bitcoin acceptance.
Few individuals knew how to send email in 1992. In the year 2000, the majority of young people could. Most older, non-tech-savvy persons could do so by 2010, thanks to major advancements in email application interfaces. Sending and receiving bitcoins is expected to go through a similar adoption cycle (although one that is likely to be quicker).

What happens if I transfer bitcoins to the incorrect address?
If a Bitcoin wallet receives an invalid address, that is, one that is not feasible on the Bitcoin network, the wallet will usually display an error message and refuse to deliver the bitcoins. The bitcoins will be sent, however, if the address is legitimate. When bitcoins are transmitted to a legitimate address, the transaction is final and irreversible.
What is the procedure for receiving bitcoins?

You first offer the person or organization who wants to pay you your public address, either as a lengthy string (such as “1K65tkPwZD67WdC1xUqi5aJkeoyS6oiJdK”) or as a QR Code. When someone donates bitcoins to your address, they will show in your Bitcoin wallet almost immediately – generally as rapidly as an email, though the transaction may take up to 10 minutes to finalize.

What is the best way to obtain bitcoins?
If you want to use Bitcoin, you should first convert some of your government-issued currency (such as dollars, euros, and so on) to bitcoins. You may do this through a variety of companies, and they all function in the same way: you enter your bank account information and then buy bitcoins. Most of these organizations also provide online “wallets” where you can store your bitcoins, however most experts advise users to retain their bitcoins in their personal wallets on their computers or cellphones. If you do this, you will have complete control over your bitcoins. Smartphone wallets are the most convenient for keeping little quantities of bitcoin – i.e., spending money.
Offering goods or services in exchange for bitcoins is another way to get them. There are also platforms that allow you to pay a portion of your salary in bitcoins, regardless of who you work for. Finally, you may mine bitcoins, although this is a pretty costly effort reserved mostly for major Bitcoin mining businesses.

What is the definition of a Bitcoin exchange?
A Bitcoin exchange allows users to trade their bitcoins for other currencies, which can include both cryptocurrencies and government-issued money. A user would often link her bank account details to the exchange in order to deposit her government-issued money, after which she will be able to buy, sell, and trade bitcoins and other currencies.

Exchanges are basically suitable for people who want to exchange bitcoins on a regular basis – they aren’t essential for people who merely want to purchase and sell products and services with Bitcoin. Unfortunately, Bitcoin exchanges have had a shady history. Many have been hacked, gone bankrupt, or had their owners vanish with the funds of their customers. In many exchanges, the bitcoins in a user’s account are really under the exchange’s control (i.e., the exchange holds the private keys), implying that the exchange owns the bitcoins.

Who is willing to take bitcoins?
The number of retailers accepting Bitcoin has grown significantly since the first “real-world” Bitcoin transaction in 2010. Dell, Overstock, and Expedia are just a few of the well-known firms that take Bitcoin. Additionally, some websites allow you to buy gift cards using bitcoins that can be redeemed at places like Amazon, Target, and Walmart.

What are some more applications for Bitcoin?
Bitcoin may be used in a variety of ways, including credit cards, cash, and wire transfers. There are, however, some applications for which Bitcoin is particularly well suited. Remittances to other nations, for example, where a person transfers money to relatives or friends in his or her home country, are a perfect fit for Bitcoin. Bitcoin offers a cheap, quick, and efficient alternative to expensive, sluggish, and inconvenient means of sending money to other nations (such as wire transfers).
Furthermore, the world’s “unbanked” population is estimated to be at 2.5 billion individuals. A weaver in rural India would simply need a smartphone to handle significant sums of money (many of the “unbanked” have affordable cellphones). People in impoverished countries might skip traditional payment methods (which are ineffective for them anyhow) and go right into 21st-century payment systems.
Bitcoin has several benefits over first-world payment methods, but the cryptocurrency’s true promise lies in areas where traditional payment systems are inadequate.

Cost of Using Bitcoin

What is the cost of using Bitcoin?
The majority of Bitcoin wallets are available for free download. Furthermore, anyone with a home computer may host their own Bitcoin node. Receiving bitcoins from other people is free, but the sender is responsible for the modest charge connected with each bitcoin transaction.
What is the cost of transmitting bitcoins to the sender?

Regardless of the magnitude of the transaction, the cost is now small — similar to a few cents. To put it another way, someone could transmit millions of dollars worth of bitcoins around the world for the cost of a few pennies. The charge is flexible and determined by the sender. The quantity of the fee can influence how soon a transaction is “verified” on the Blockchain. The bigger the price, the faster it will be applied, however even a fee of a few cents will now result in a transaction being completed within minutes.

Who is in charge of collecting the fees?
Fees are added to a transaction, and when a miner verifies it in a block uploaded to the Blockchain, she receives the fee as well as the block reward. For example, if I transmit 3 bitcoins to someone, my wallet will deduct the cost (which may be.0001 bitcoins). The miner will then receive the fee, which will be included in the next block uploaded to the Blockchain.

What if my Bitcoin transaction doesn’t contain a fee?
It is possible to transmit bitcoins without paying a charge to another address. If this happens, the transaction will almost certainly be delayed before being validated on the Blockchain. This is because there will be no incentive for miners to include it in a block because there would be no revenue for doing so. It’s still conceivable that it’ll be verified, but it might take hours or days.
Bitcoin Mining

What is Bitcoin mining, and how does it work?
The process of adding new bitcoins to the Bitcoin network, as well as the act of securing the Bitcoin network, is known as bitcoin mining. It’s termed mining because Bitcoin was purposefully meant to resemble precious metals like gold and silver, and just as “adding” new gold and silver to the world’s supply is referred to as mining, so is “adding” new bitcoins to the world’s supply. Bitcoin’s supply, like that of precious metals, is restricted, and no authority can control it.
To utilize Bitcoin in everyday life, the common user does not need to comprehend mining. Mining, on the other hand, is an important feature of Bitcoin; it maintains the Bitcoin network safe and guarantees the orderly addition of new bitcoins.

What is Bitcoin mining and how does it work?
Security is one of the possible drawbacks of a digital money. Most attempts to secure a digital currency prior to Bitcoin featured a central control center that authenticated transactions and secured the network from hackers and assaults. A centralized architecture like this, on the other hand, is vulnerable for numerous reasons: a government agency may easily shut it down by closing that control center; hackers can focus their assaults on a single site; and the entire network has a single point of failure (the command center).
Bitcoin approaches the challenge of network security in an entirely new way. Instead of a centralized control center run by a single organization, Bitcoin uses a “mining” process that involves people from all over the world. In this procedure, powerful computers controlled by mining businesses or even individuals compete to solve complex mathematical problems, with the winner getting a predetermined quantity of bitcoins from the network. The goal of this competition is to safeguard the network by preventing individuals from confirming incorrect transactions or counterfeiting bitcoins. Participants will get fresh bitcoins as a prize for participating. As a result, people all across the world have an incentive to help make the Bitcoin network more secure.
The method is hard, but the computing power required to solve these challenges, along with the total computing power of all machines attempting to solve these problems, makes creating fraudulent Bitcoin transactions very impossible. Someone with greater computer power than the majority of the Bitcoin network, which is large and expanding every day, would be able to do so. In reality, the expense of “overpowering” the Bitcoin network considerably outweighs the possible advantages.

What is the rate at which new bitcoins are introduced to the Bitcoin network?
The Bitcoin network is set up in such a way that these mathematical problems are solved every 10 minutes or so (if problems are being solved too quickly, they get harder, and if too slowly, they get easier).

When bitcoins are mined, how many new bitcoins are created?
Over time, the quantity of bitcoins rewarded for mining diminishes. The “block reward” was set at 50 bitcoins from the start. In 2012, it was halved to 25 bitcoins, and it will be halved every four years after that (every 210,000 blocks, to be exact). Most bitcoins will have been contributed to the network by the 2030s, as seen in this graph:
Over time, the Bitcoin network contributes a diminishing amount of bitcoins.

What is the time frame for adding additional bitcoins to the network?
All bitcoins will have been mined by the year 2140, and there will be no more mining awards.

Why weren’t all 21 million bitcoins distributed at the same time?
Satoshi Nakamoto purposefully designed the Bitcoin network so that bitcoins would be added steadily over time. This was done for a variety of reasons, including:
1) If all bitcoins had been contributed at the start of the network, a small number of people may have possessed them all, discouraging others from adopting Bitcoin.
2) Allowing bitcoins to be the reward for mining has created an incentive for individuals all over the world to work together to safeguard the network.
3) The gradual addition of bitcoins over time demonstrates a control over the money supply akin to precious metals, making each bitcoin more valuable before Bitcoin becomes mainstream.

Is it possible to mine bitcoins on a personal computer?
It was feasible to mine Bitcoin successfully on any basic personal computer when it initially started. However, as the Bitcoin network has grown, the mathematical problems that must be solved have become increasingly difficult. As a result, mining bitcoins requires a specialized computer, and the energy and computer costs usually make it unprofitable for an individual to do so. The majority of mining is now done in “pools,” where multiple people pool their resources and share the block reward.

What will happen when it is no longer possible to mine new bitcoins?
The only way to make money mining at that point will be through the fees associated with each bitcoin transaction. However, most experts believe that by then, the network will have grown sufficiently to ensure that mining will continue to be a profitable endeavor for those who participate.
Anonymity of Using Bitcoin

Is Bitcoin a private currency?
When Bitcoin originally gained popularity outside of the technical community, it was dubbed a “anonymous” network because you could spend bitcoins without anybody being able to track your purchase back to you. “Reports of Bitcoin’s anonymity have been vastly overblown,” to paraphrase a cliché. As you might expect, a network that logs every transaction isn’t completely anonymous. Bitcoin is more accurately described as “pseudonymous.”
What does it imply when someone refers to Bitcoin as “pseudonymous”?

Bitcoin is designed to function similarly to cash, and when you spend cash, you don’t have to reveal your personal information to the merchant. Similarly, unlike with credit cards, you are not required to reveal your identity when using bitcoins. Although you may use another identity to spend bitcoins, if somebody ties you to that identity, they will know you spent those bitcoins. Remember that the Blockchain keeps track of all transactions and links them together to prevent “double-spends.” As a result, every bitcoin transaction from one address to another is logged and recorded. The chain linking every transaction ever recorded in Bitcoin history could theoretically be traced.

How could a bitcoin transaction be linked to a specific person?
Let’s imagine Alice wants to buy a software download online with bitcoins but doesn’t want anyone to know. So she creates a fake account on the site and uses her bitcoins to purchase the product. The bitcoins she spends, on the other hand, are ones she bought with her true name from a Bitcoin exchange. If someone was prepared to put in the time and effort, they could link those transactions and determine that Alice was most likely the one who bought that merchandise.
Bitcoin transactions are preferable to credit card transactions in that they do not need a person to provide all of his personal information every time he wants to buy a cup of coffee. However, it is not genuinely anonymous, and no one should take it for such.

Security of Bitcoin

Is it safe to use Bitcoin?
There is no such thing as a completely secure financial payment system. There are several ways in which security may be hacked in any traditional system of financial transactions, as we have all seen in the headlines. Massive cyberattacks, bank robberies, and other crimes have all occurred over the years as examples. The security of banks – both the buildings that hold currency and the network security that prevents hackers; the security of merchants who record and store transactions; the physical security associated with owning a credit card; and the security practices of the individuals who use the currency are some of the weak points in traditional payment systems. Bitcoin security, on the other hand, has only two possible points of failure: the Bitcoin network’s security and the security of individual bitcoin wallets.

Is it possible to hack the Bitcoin network?
One of the most important features of the Bitcoin network is its high level of security. The Blockchain, which is saved on hundreds of computers across the world, contains every transaction ever recorded in Bitcoin history. Attempting to change such transactions in one’s favor would require significantly more computer power than the potential payout. Furthermore, the encryption utilized to safeguard each transaction is comparable to, if not superior to, that employed by large financial institutions and banks. If the encryption that underpins Bitcoin is breached, the world will face far greater financial issues than Bitcoin fraud.

Is it possible to hack Bitcoin wallets?
Wallets, like any program, are vulnerable to hacking since they are built by a variety of software developers and managed by individuals. Because of the way Bitcoin is currently utilized, the owner is solely responsible for the security of his or her bitcoins. This spreads the risk: a hacker would have to get into thousands of wallets to get the same amount of money he could get from a single bank or credit card firm. However, if a person uses a poorly-designed wallet, fails to secure his private key, has her computer where the wallet is stored hacked, or otherwise fails to follow appropriate security protocols (strong passwords, etc. ), his bitcoins may not be in his hands for long. Many people are unprepared for this degree of accountability in an era where financial institutions bear the brunt of security responsibilities. Fortunately, numerous firms are working to build Bitcoin wallets that are becoming increasingly simple to use and safe.

Are there any other possibilities for me to lose my bitcoins?
Trusting one’s private keys to a third party, such as an online wallet or Bitcoin exchange, is the most common way for one to lose their bitcoins. Using an internet service like this can be advantageous in that it places responsibility for security on a reputed “expert” rather to the newbie, but it can be disastrous if that third party is inept, unethical, or both. More than one exchange and online wallet have lost user cash in Bitcoin’s brief lifetime. Some have concluded that Bitcoin is vulnerable as a result of this. The issue was not with the Bitcoin network, but with those who were trusted with other people’s bitcoins.

What is the most secure way to store my bitcoins?
Because Bitcoin is entirely based on the Internet, conventional Internet security standards apply: using strong passwords, storing passwords securely, protecting your equipment from viruses and hackers, and using two-factor authentication when appropriate. Furthermore, people who utilize online wallets and exchanges should only maintain a limited quantity on those sites because you don’t have control over the bitcoins’ private keys. Finally, big sums of bitcoins should be held mostly in paper wallets to avoid being stolen by hackers.

Value of Bitcoin

What is a bitcoin’s inherent value?
The value of a bitcoin is determined by the community. This may appear to be a circular argument, but it is not. Any currency’s “intrinsic” worth – whether it’s dollars, gold, or yen, or any item like potatoes, iron, or bubble gum – is determined by what people are prepared to give up in exchange for it. The reasons for why we value anything may vary (government support, item qualities, capacity to be used to build something else, etc. ), but the worth of anything is determined by what two or more people agree on. Bitcoin’s value is derived from the network’s effectiveness as well as the restricted amount of bitcoins.

But, because Bitcoin isn’t tangible, can it truly be said to have inherent value?
When people talk about “intrinsic” worth, they frequently refer to a physical feature that an item possesses. Gold, for example, is valuable because it can be used in electronics and is widely utilized in jewelry. However, if someone wants something, it has worth — and when two individuals desire something, the value is more correctly stated as the maximum price someone is prepared to pay to have it.
Returning to Bitcoin, individuals have determined that it has value since it is a simple and inexpensive means of transferring money. If a better way to achieve what Bitcoin does comes along in the future, Bitcoin’s “intrinsic” value will almost certainly drop to zero. However, it has worth as long as people find it beneficial. Like any other currency or commodity.

Isn’t 21 million bitcoins insufficient for billions of users?
A widespread misconception about money is that it is possible to have too little of it. Some would claim that if a civilization has 100 million inhabitants, having just 10 million units of money would be untenable. There wouldn’t be enough to go around for everyone. This is not the case, though. Any amount of money might be used in such civilization as long as the money is sufficiently divisible.

What does it imply when a currency must be divisible enough?
Consider the scenario described above (100 million people/$10 million). If all of the money were distributed equally, each person would receive ten cents ($10 million divided by 100 million individuals). That’s not going to work, is it? But what if the smallest coin was worth 1/1,000,000 of a dollar instead of 1/100 of a dollar (i.e. one cent)? Let’s call it a “small” denomination. Every citizen in this just society would have 100,000 “tinys” in that situation. It should be obvious at this point that a pack of gum could be 1 tiny, a gallon of milk could be 10 tinys, and so on.

What is Bitcoin’s divisibility?
Bitcoin is now divisible to the eighth decimal place (.00000001); the smallest unit is known as a “satoshi,” after the cryptocurrency’s founder. So if I possess one bitcoin, I own 100,000,000 satoshis, and the Bitcoin network will eventually have 21 quadrillion satoshis accessible. A book may cost a few satoshis, while a car could cost a few thousand if the value of one bitcoin continues to climb. Bitcoin may be used for transactions of any magnitude, regardless of how much or how little it is worth.
Also keep in mind that Bitcoin’s present divisibility might be raised in future network upgrades, so the possibilities are endless.
Objections to Bitcoin

Is Bitcoin a “real” currency?
People have a hard time accepting a cash they can’t grasp in their hands as legitimate. Some people, particularly proponents of precious metals, believe that “if you can’t handle it, you don’t possess it.” And in the case of precious metals, the adage holds a lot of truth. Many individuals have the same natural mindset even when discussing a government-issued money like the US dollar, which is largely utilized electronically. In the back of their minds is the idea that if they ever needed money, they could cash out all of their savings and assets and stuff it beneath their mattresses. (Of course, most financial institutions will not allow consumers to withdraw significant sums of money.)
Bitcoin, on the other hand, is in many respects simpler to really “keep” than most other types of cash, particularly government-issued currencies. When it comes to Bitcoin, if you have the private keys, you have complete and entire power over the currency. Unless you give them up, no one else will ever be able to obtain them (either through bad security, by force, or voluntarily). All of your money in the bank, on the other hand, isn’t truly yours; it belongs to the bank, which promises to return it to you if you ask…with a few conditions (like the limit on withdrawals).
Bitcoin’s non-physicality is mostly a psychological issue. Before we consider something “real,” we prefer to be able to touch, feel, and see it first. None of this is possible with Bitcoin. It may, however, be used to buy things, making it just as real as any other cash.

Isn’t Bitcoin only used by crooks and drug dealers?
Bitcoin has been connected with criminal activity in the public eye since its inception. Many criminals have exploited Bitcoin in their unlawful activities, and this is real. But do you have any idea which money thieves love more than any other in the world? In the form of currency, the US dollar. Bitcoin may be used for bad reasons since it has qualities comparable to currency. In truth, every money ever created has been exploited for illegal reasons; the issue is with the criminals, not with the currency. All of this increased criminal behavior demonstrates is that a money is popular and simple to use, which is precisely what we want in a currency, right?

What causes the price to fluctuate so much?
When Bitcoin first became well known, one of its most notable characteristics was its price volatility. You could get bitcoins for nearly nothing in 2010. They were valued over $1,200 per bitcoin at the end of 2013, and they are currently hovering in the $200s. Isn’t this an indication of a shaky currency, or at the very least an underlying issue?
The fact is that Bitcoin is still a very new and experimental currency. No one knows how it will be used or how much it will be utilized in the future. As a result, establishing its worth will be a risky effort. The price of Bitcoin is expected to steady as more people learn about it and use it (and it already has to some degree).

Isn’t Bitcoin prohibited in some jurisdictions?
Bitcoin’s legality has been questioned in a number of nations, including the United States. Some Bitcoin critics say that only the government has the authority to create money, and that any privately generated currency, such as Bitcoin, is thus unlawful. However, the Internal Revenue Service of the United States announced in March 2014 that bitcoins should be considered as a commodity for tax purposes, implying their legality — how can you tax something that is unlawful to own?
Governments in nations like China and Russia have made harsh remarks about Bitcoin in the past, although many of these pronouncements are contradictory and/or ambiguous. Owning bitcoins is outlawed in just a few nations at the time of writing, and more and more governments are officially proclaiming it lawful to possess and use them.

The Future of Bitcoin

What will Bitcoin’s future look like?
Bitcoin is a fascinating technology with the potential to revolutionize the way people use money. It is, however, fundamentally an experiment. As a result, it may be superseded by superior technology in the future, or it may be discovered to have a serious technological defect. Although the latter is doubtful given that the network has already processed millions of transactions, the former is always a possibility. Furthermore, governments may determine that Bitcoin poses a danger to their power systems and enact legislation to prohibit its usage. Despite the fact that many bright minds and a lot of money are being poured into the growth of Bitcoin, there is no assurance that it will thrive in the marketplace.

Is it wise to invest in bitcoins?
There is no way to predict what the price of bitcoins will be in the future because Bitcoin is still new and experimental. This book focuses on Bitcoin as a payment mechanism, a money, and a technology; it does not take an investing stance on Bitcoin. Many people assume that the price of bitcoins will rise over time as more people use them and the supply of bitcoins decreases, but no one can forecast the future.

Will Bitcoin eventually supplant the dollar?
Most likely not. The dollar will eventually fail, as will other government-issued currencies. There’s no way of knowing if it’ll be replaced by Bitcoin, the yen, or another currency. It might be replaced by a cryptocurrency that isn’t even on the market yet, or by a hybrid government-issued cryptocurrency.

Will our present credit card payment networks be replaced by the Blockchain?
Although Bitcoin is unlikely to totally replace government-issued currencies, the Bitcoin network has the potential to replace, or at the very least considerably enhance, established credit card payment networks. Financial institutions have taken note of the Bitcoin network’s inherent efficiency and low-cost maintenance, and many of them are looking into the Blockchain to see whether its ideas can be applied to their own networks.
