Cryptocurrency is a type of virtual currency that utilizes cryptography to validate and secure transactions that are digitally recorded on a distributed ledger, such as a blockchain. Bitcoin is one example of a convertible virtual currency. Bitcoin can be digitally traded between users and can be purchased for, or exchanged into, U.
The sale or other exchange of virtual currencies, or the use of virtual currencies to pay for goods or services, or holding virtual currencies as an investment, generally has tax consequences that could result in tax liability. For more information regarding the general tax principles that apply to virtual currencies, you can also refer to the following IRS Publications:.
There are several modes which wallets can operate in. They have an inverse relationship with regards to trustlessness and computational requirements. Third-party internet services called online wallets offer similar functionality but may be easier to use. In this case, credentials to access funds are stored with the online wallet provider rather than on the user's hardware.
A malicious provider or a breach in server security may cause entrusted bitcoins to be stolen. An example of such a security breach occurred with Mt. Gox in Physical wallets store the credentials necessary to spend bitcoins offline and can be as simple as a paper printout of the private key:  : ch. A paper wallet is created with a keypair generated on a computer with no internet connection ; the private key is written or printed onto the paper [h] and then erased from the computer.
The paper wallet can then be stored in a safe physical location for later retrieval. Bitcoins stored using a paper wallet are said to be in cold storage. Physical wallets can also take the form of metal token coins  with a private key accessible under a security hologram in a recess struck on the reverse side.
Another type of physical wallet called a hardware wallet keeps credentials offline while facilitating transactions. Hardware wallets never expose their private keys, keeping bitcoins in cold storage even when used with computers that may be compromised by malware. The first wallet program, simply named Bitcoin , and sometimes referred to as the Satoshi client , was released in by Satoshi Nakamoto as open-source software.
Bitcoin Core is, perhaps, the best known implementation or client. On 1 August , Bitcoin Cash was created as result of a hard fork. On 24 October another hard fork, Bitcoin Gold , was created. Bitcoin Gold changes the proof-of-work algorithm used in mining, as the developers felt that mining had become too specialized.
Bitcoin is decentralized thus: . Researchers have pointed out at a "trend towards centralization". Although bitcoin can be sent directly from user to user, in practice intermediaries are widely used. The pool has voluntarily capped their hashing power at According to researchers, other parts of the ecosystem are also "controlled by a small set of entities", notably the maintenance of the client software, online wallets and simplified payment verification SPV clients.
Bitcoin is pseudonymous , meaning that funds are not tied to real-world entities but rather bitcoin addresses. Owners of bitcoin addresses are not explicitly identified, but all transactions on the blockchain are public. In addition, transactions can be linked to individuals and companies through "idioms of use" e. Wallets and similar software technically handle all bitcoins as equivalent, establishing the basic level of fungibility. Researchers have pointed out that the history of each bitcoin is registered and publicly available in the blockchain ledger, and that some users may refuse to accept bitcoins coming from controversial transactions, which would harm bitcoin's fungibility.
Gox froze accounts of users who deposited bitcoins that were known to have just been stolen. The blocks in the blockchain were originally limited to 32 megabytes in size. The block size limit of one megabyte was introduced by Satoshi Nakamoto in Eventually the block size limit of one megabyte created problems for transaction processing, such as increasing transaction fees and delayed processing of transactions.
Satoshi Nakamoto stated in his white paper that: "The root problem with conventional currencies is all the trust that's required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust.
According to the European Central Bank , the decentralization of money offered by bitcoin has its theoretical roots in the Austrian school of economics , especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined ,  in which Hayek advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks.
According to The New York Times , libertarians and anarchists were attracted to the idea. Early bitcoin supporter Roger Ver said: "At first, almost everyone who got involved did so for philosophical reasons. We saw bitcoin as a great idea, as a way to separate money from the state.
Nigel Dodd argues in The Social Life of Bitcoin that the essence of the bitcoin ideology is to remove money from social, as well as governmental, control. The declaration includes a message of crypto-anarchism with the words: "Bitcoin is inherently anti-establishment, anti-system, and anti-state. Bitcoin undermines governments and disrupts institutions because bitcoin is fundamentally humanitarian.
David Golumbia says that the ideas influencing bitcoin advocates emerge from right-wing extremist movements such as the Liberty Lobby and the John Birch Society and their anti-Central Bank rhetoric, or, more recently, Ron Paul and Tea Party -style libertarianism. It takes control back from central authorities. It's revolutionary. A study of Google Trends data found correlations between bitcoin-related searches and ones related to computer programming and illegal activity, but not libertarianism or investment topics.
Bitcoin is a digital asset designed to work in peer-to-peer transactions as a currency. Economists define money as serving the following three purposes: a store of value , a medium of exchange , and a unit of account. Shiller writes that bitcoin has potential as a unit of account for measuring the relative value of goods, as with Chile's Unidad de Fomento , but that "Bitcoin in its present form [ According to research by Cambridge University , between 2.
The number of users has grown significantly since , when there were ,—1. The overwhelming majority of bitcoin transactions take place on a cryptocurrency exchange , rather than being used in transactions with merchants. Prices are not usually quoted in units of bitcoin and many trades involve one, or sometimes two, conversions into conventional currencies.
In and bitcoin's acceptance among major online retailers included only three of the top U. Bitcoin is "not actually usable" for retail transactions because of high costs and the inability to process chargebacks , according to Nicholas Weaver, a researcher quoted by Bloomberg.
High price volatility and transaction fees make paying for small retail purchases with bitcoin impractical, according to economist Kim Grauer. However, bitcoin continues to be used for large-item purchases on sites such as Overstock.
Bitcoins can be bought on digital currency exchanges. Per researchers, "there is little sign of bitcoin use" in international remittances despite high fees charged by banks and Western Union who compete in this market. In , the National Australia Bank closed accounts of businesses with ties to bitcoin,  and HSBC refused to serve a hedge fund with links to bitcoin.
On 10 December , the Chicago Board Options Exchange started trading bitcoin futures,  followed by the Chicago Mercantile Exchange , which started trading bitcoin futures on 17 December The request was motivated by oil company's goal to pay its suppliers.
The Winklevoss twins have purchased bitcoin. Other methods of investment are bitcoin funds. The first regulated bitcoin fund was established in Jersey in July and approved by the Jersey Financial Services Commission. Forbes named bitcoin the best investment of According to bitinfocharts. In August , MicroStrategy invested in Bitcoin. The price of bitcoins has gone through cycles of appreciation and depreciation referred to by some as bubbles and busts.
According to Mark T. Unusual for an asset, bitcoin weekend trading during December was higher than for weekdays. Because of bitcoin's decentralized nature and its trading on online exchanges located in many countries, regulation of bitcoin has been difficult. However, the use of bitcoin can be criminalized, and shutting down exchanges and the peer-to-peer economy in a given country would constitute a de facto ban.
Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems. In October , the Islamic Republic News Agency announced pending regulations that would require bitcoin miners in Iran to sell bitcoin to the Central Bank of Iran , and the central bank would use it for imports.
The U. Commodity Futures Trading Commission has issued four "Customer Advisories" for bitcoin and related investments. Securities and Exchange Commission warned that investments involving bitcoin might have high rates of fraud, and that investors might be solicited on social media sites. The European Banking Authority issued a warning in focusing on the lack of regulation of bitcoin, the chance that exchanges would be hacked, the volatility of bitcoin's price, and general fraud.
An official investigation into bitcoin traders was reported in May Justice Department launched an investigation into possible price manipulation, including the techniques of spoofing and wash trades. Following the first delivery date in January , the CME requested extensive detailed trading information but several of the exchanges refused to provide it and later provided only limited data.
The Commodity Futures Trading Commission then subpoenaed the data from the exchanges. State and provincial securities regulators, coordinated through the North American Securities Administrators Association , are investigating "bitcoin scams" and ICOs in 40 jurisdictions.
Academic research published in the Journal of Monetary Economics concluded that price manipulation occurred during the Mt Gox bitcoin theft and that the market remains vulnerable to manipulation. Research by John M. Griffin and Amin Shams in suggests that trading associated with increases in the amount of the Tether cryptocurrency and associated trading at the Bitfinex exchange account for about half of the price increase in bitcoin in late The Bank for International Settlements summarized several criticisms of bitcoin in Chapter V of their annual report.
The criticisms include the lack of stability in bitcoin's price, the high energy consumption, high and variable transactions costs, the poor security and fraud at cryptocurrency exchanges, vulnerability to debasement from forking , and the influence of miners. In , The Economist described these criticisms as unfair, since bitcoin had been relatively stable during that year, and the shady image may have compelled users to overlook the capabilities of the blockchain technology.
Bitcoin, along with other cryptocurrencies, has been described as an economic bubble by at least eight Nobel Memorial Prize in Economic Sciences laureates at various times, including Robert Shiller on 1 March ,  Joseph Stiglitz on 29 November ,  and Richard Thaler on 21 December Bitcoin has been criticized for the amount of electricity consumed by mining.
As of [update] , The Economist estimated that even if all miners used modern facilities, the combined electricity consumption would be In July BBC reported bitcoin consumes about 7 gigawatts, 0. To lower the costs, bitcoin miners have set up in places like Iceland where geothermal energy is cheap and cooling Arctic air is free. Concerns about bitcoin's environmental impact relate bitcoin's energy consumption to carbon emissions.
The results of recent studies analyzing bitcoin's carbon footprint vary. Journalists, economists, investors, and the central bank of Estonia have voiced concerns that bitcoin is a Ponzi scheme. Bitcoin is vulnerable to theft through phishing , scamming , and hacking. The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and the media.
Senate held a hearing on virtual currencies in November Several news outlets have asserted that the popularity of bitcoins hinges on the ability to use them to purchase illegal goods. In , researchers at the University of Kentucky found "robust evidence that computer programming enthusiasts and illegal activity drive interest in bitcoin, and find limited or no support for political and investment motives".
There were an estimated 24 million bitcoin users primarily using bitcoin for illegal activity. In , Abkhazia placed a ban on Bitcoin. Velde, Senior Economist at the Chicago Fed , described it as "an elegant solution to the problem of creating a digital currency". Louis , stated that bitcoin is a threat to the establishment, which he argues is a good thing for the Federal Reserve System and other central banks , because it prompts these institutions to operate sound policies.
PayPal President David A. Marcus calls bitcoin a "great place to put assets". Bitcoin Core is free and open-source software that serves as a bitcoin node the set of which form the bitcoin network and provides a bitcoin wallet which fully verifies payments. It is considered to be bitcoin's reference implementation. Bitcoin Core includes a transaction verification engine and connects to the bitcoin network as a full node. It does not facilitate the buying or selling of bitcoin.
It allows users to generate QR codes to receive payment. The software validates the entire blockchain , which includes all bitcoin transactions ever. This distributed ledger which has reached more than gigabytes in size as of Jan , must be downloaded or synchronized before full participation of the client may occur. It also provides access to testnet, a global testing environment that imitates the bitcoin main network using an alternative blockchain where valueless "test bitcoins" are used.
Regtest or Regression Test Mode creates a private blockchain which is used as a local testing environment. Checkpoints which have been hard coded into the client are used only to prevent Denial of Service attacks against nodes which are initially syncing the chain. For this reason the checkpoints included are only as of several years ago. This limited the maximum network capacity to about three transactions per second.
A network alert system was included by Satoshi Nakamoto as a way of informing users of important news regarding bitcoin. It had become obsolete as news on bitcoin is now widely disseminated. Bitcoin Core includes a scripting language inspired by Forth that can define transactions and specify parameters.
Two stacks are used - main and alt. Looping is forbidden. Bitcoin Core uses OpenTimestamps to timestamp merge commits. The original creator of the bitcoin client has described their approach to the software's authorship as it being written first to prove to themselves that the concept of purely peer-to-peer electronic cash was valid and that a paper with solutions could be written. The lead developer is Wladimir J. Andresen left the role of lead developer for bitcoin to work on the strategic development of its technology.
In Charles Stross ' science fiction novel, Neptune's Brood , the universal interstellar payment system is known as "bitcoin" and operates using cryptography. Bitcoin was obscure back then, and I figured had just enough name recognition to be a useful term for an interstellar currency: it'd clue people in that it was a networked digital currency.
The documentary The Rise and Rise of Bitcoin portrays the diversity of motives behind the use of bitcoin by interviewing people who use it. These include a computer programmer and a drug dealer. It covers studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh. Authors are also asked to include a personal bitcoin address in the first page of their papers.

The timestamp of the block is This block is unlike all other blocks in that it does not have a previous block to reference. The fact is that gold miners are rewarded for producing gold, while bitcoin miners are not rewarded for producing bitcoins; they are rewarded for their record-keeping services. Usually, the public key or bitcoin address is also printed, so that a holder of a paper wallet can check or add funds without exposing the private key to a device.

The public key comparable to a bank account number serves as the address which is published to the world and to which others may send bitcoins. The private key comparable to an ATM PIN is meant to be a guarded secret and only used to authorize bitcoin transmissions. Bitcoin keys should not be confused with a bitcoin wallet, which is a physical or digital device that facilitates the trading of bitcoin and allows users to track ownership of coins.
The term "wallet" is a bit misleading, as bitcoin's decentralized nature means that it is never stored "in" a wallet, but rather decentrally on a blockchain. Bitcoin is one of the first digital currencies to use peer-to-peer technology to facilitate instant payments. The independent individuals and companies who own the governing computing power and participate in the bitcoin network—bitcoin "miners"—are in charge of processing the transactions on the blockchain and are motivated by rewards the release of new bitcoin and transaction fees paid in bitcoin.
These miners can be thought of as the decentralized authority enforcing the credibility of the bitcoin network. New bitcoin is released to the miners at a fixed, but periodically declining rate. There are only 21 million bitcoin that can be mined in total. As of January 30, , there are approximately 18,, bitcoin in existence and 2,, bitcoin left to be mined. In this way, bitcoin other cryptocurrencies operate differently from fiat currency; in centralized banking systems, currency is released at a rate matching the growth in goods; this system is intended to maintain price stability.
A decentralized system, like bitcoin, sets the release rate ahead of time and according to an algorithm. Generally, mining requires the solving of computationally difficult puzzles in order to discover a new block , which is added to the blockchain. Bitcoin mining adds and verifies transaction records across the network. For adding blocks to the blockchain, miners are rewarded with a few bitcoins; the reward is halved every , blocks.
The block reward was 50 new bitcoins in On May 11th, , the third halving occurred, bringing the reward for each block discovery down to 6. A variety of hardware can be used to mine bitcoin. However, some yield higher rewards than others. These elaborate mining processors are known as "mining rigs. One bitcoin is divisible to eight decimal places millionths of one bitcoin , and this smallest unit is referred to as a Satoshi.
The domain name bitcoin. Today, at least, this domain is "WhoisGuard Protected," meaning the identity of the person who registered it is not public information. This now-famous whitepaper published on bitcoin. The first Bitcoin block is mined, Block 0. No one knows who invented bitcoin, or at least not conclusively. In the years since that time, many individuals have either claimed to be or have been suggested as the real-life people behind the pseudonym, but as of January , the true identity or identities behind Satoshi remains obscured.
Although it is tempting to believe the media's spin that Satoshi Nakamoto is a solitary, quixotic genius who created Bitcoin out of thin air, such innovations do not typically happen in a vacuum. All major scientific discoveries, no matter how original-seeming, were built on previously existing research.
Perhaps unsurprisingly, many of the individuals behind the other projects named above have been speculated to have also had a part in creating bitcoin. There are a few possible motivations for bitcoin's inventor deciding to keep their identity secret. Another reason could be the potential for bitcoin to cause a major disruption in the current banking and monetary systems. If bitcoin were to gain mass adoption, the system could surpass nations' sovereign fiat currencies.
This threat to existing currency could motivate governments to want to take legal action against bitcoin's creator. The other reason is safety. One may conclude that only Satoshi and perhaps a few other people were mining through and that they possess a majority of that stash of bitcoin. Someone in possession of that much bitcoin could become a target of criminals, especially since bitcoins are less like stocks and more like cash, where the private keys needed to authorize spending could be printed out and literally kept under a mattress.
Bitcoins can be accepted as a means of payment for products sold or services provided. An online business can easily accept bitcoins by adding this payment option to its other online payment options: credit cards, PayPal, etc.
Those who are self-employed can get paid for a job related to bitcoin. There are a number of ways to achieve this, such as creating any internet service and adding your bitcoin wallet address to the site as a form of payment. There are also several websites and job boards that are dedicated to digital currencies:. There are many bitcoin supporters who believe that digital currency is the future. Many individuals who endorse bitcoin believe that it facilitates a much faster, low-fee payment system for transactions across the globe.
Indeed, one of the primary reasons for the growth of digital currencies like bitcoin is that they can act as an alternative to national fiat money and traditional commodities like gold. In March , the IRS stated that all virtual currencies, including bitcoins, would be taxed as property rather than currency. Gains or losses from bitcoins held as capital will be realized as capital gains or losses, while bitcoins held as inventory will incur ordinary gains or losses.
The sale of bitcoins that you mined or purchased from another party, or the use of bitcoins to pay for goods or services, are examples of transactions that can be taxed. Like any other asset, the principle of buying low and selling high applies to bitcoins. The most popular way of amassing the currency is through buying on a bitcoin exchange, but there are many other ways to earn and own bitcoins.
Although Bitcoin was not designed as a normal equity investment no shares have been issued , some speculative investors were drawn to the digital currency after it appreciated rapidly in May and again in November Thus, many people purchase bitcoin for its investment value rather than its ability to act as a medium of exchange. However, the lack of guaranteed value and its digital nature means the purchase and use of bitcoins carries several inherent risks.
The concept of a virtual currency is still novel and, compared to traditional investments, bitcoin doesn't have much of a long-term track record or history of credibility to back it. With their increasing popularity, bitcoins are becoming less experimental every day; still, after only a decade, all digital currencies still remain in a development phase. Investing money into bitcoin in any of its many guises is not for the risk-averse. Bitcoins are a rival to government currency and may be used for black market transactions, money laundering, illegal activities, or tax evasion.
As a result, governments may seek to regulate, restrict, or ban the use and sale of bitcoins and some already have. Others are coming up with various rules. For example, in , the New York State Department of Financial Services finalized regulations that would require companies dealing with the buy, sell, transfer, or storage of bitcoins to record the identity of customers, have a compliance officer, and maintain capital reserves.
The lack of uniform regulations about bitcoins and other virtual currency raises questions over their longevity, liquidity, and universality. Most individuals who own and use bitcoin have not acquired their tokens through mining operations. Rather, they buy and sell bitcoin and other digital currencies on any of a number of popular online markets, known as bitcoin exchanges.
Bitcoin exchanges are entirely digital and, as with any virtual system, are at risk from hackers, malware, and operational glitches. If a thief gains access to a bitcoin owner's computer hard drive and steals their private encryption key, they could transfer the stolen bitcoin to another account. Users can prevent this only if bitcoins are stored on a computer that is not connected to the internet, or else by choosing to use a paper wallet —printing out the bitcoin private keys and addresses, and not keeping them on a computer at all.
Hackers can also target bitcoin exchanges, gaining access to thousands of accounts and digital wallets where bitcoins are stored. One especially notorious hacking incident took place in , when Mt. Gox, a bitcoin exchange in Japan, was forced to close down after millions of dollars worth of bitcoins were stolen. This is particularly problematic given that all Bitcoin transactions are permanent and irreversible.
It's like dealing with cash: Any transaction carried out with bitcoins can only be reversed if the person who has received them refunds them. There is no third party or a payment processor, as in the case of a debit or credit card—hence, no source of protection or appeal if there is a problem. Some investments are insured through the Securities Investor Protection Corporation. Generally speaking, bitcoin exchanges and bitcoin accounts are not insured by any type of federal or government program.
In , prime dealer and trading platform SFOX announced it would be able to provide bitcoin investors with FDIC insurance, but only for the portion of transactions involving cash. While bitcoin uses private key encryption to verify owners and register transactions, fraudsters and scammers may attempt to sell false bitcoins. While sending to a hardware wallet is something most all wallets can do, being able to pair with one is a unique feature.
This feature enables you to be able to send and receive directly to and from a hardware wallet. Most wallets have the ability to send and receive with legacy bitcoin addresses. Legacy addresses start with 1 or 3 as opposed to starting with bc1. Without legacy address support, you may not be able to receive bitcoin from older wallets or exchanges. Some wallets support transactions on the Lightning Network. The Lightning Network is new and somewhat experimental.
It supports transferring bitcoin without having to record each transaction on the blockchain, resulting in faster transactions and lower fees. Some wallets have the ability to require more than one key to authorize a transaction. This can be used to divide responsibility and control over multiple parties. Some wallets support SegWit, which uses block chain space more efficiently.
This helps reduce fees paid by helping the Bitcoin network scale and sets the foundation for second layer solutions such as the Lightning Network. Make a donation.

Bitcoin is one kind of digital currency or cryptocurrency, a medium of exchange that exists exclusively online. The currency broke into mainstream consciousness in , as its price ran up thousands of dollars over the course of the year. Bitcoin debuted in , when the software underpinning the currency was released. Its origins are a bit mysterious, however, and a person or perhaps group known as Satoshi Nakamoto claims the credit for unveiling the cryptocurrency.
Bitcoin operates on a decentralized computer network or distributed ledger called a blockchain, which manages and tracks the currency. Think of the distributed ledger like a huge public record of transactions taking place in the currency. The networked computers verify the transactions, ensuring the integrity of the data and the ownership of bitcoins.
This decentralized network is a huge part of the appeal of Bitcoin and other cryptocurrencies. Users can exchange money to and from other users, and the lack of a central bank to manage the currency makes the currency almost autonomous. This autonomy means that the currency, at least theoretically, can avoid the interference of governments and central banks. Bitcoin can operate mostly anonymously.
Some computers called miners are specially outfitted with high-powered processors that can chew through transactions and earn a part of a bitcoin. So Bitcoin requires a lot of processing power to maintain the network and a lot of electricity to run those computers.
In the absence of such a change, experts expect the remaining number of bitcoins to be mined out around the year When this occurs, miners will be rewarded solely with a fee for processing transactions. While the number of bitcoins may be limited, each whole bitcoin can be split into much smaller units. A bitcoin can be officially divided into as many as one hundred million parts, which are called satoshi in honor of the mysterious founder. In practice, however, bitcoins are divided into even finer divisions to facilitate payments of very small amounts of real currency.
Bitcoin is just one type of cryptocurrency, and literally thousands more have been created. Some of the most popular include Ethereum, Litecoin and Ripple. Users can hold and spend bitcoins from a cryptocurrency wallet. A wallet is like a personalized location on the distributed ledger that refers to only your currency holdings. When you acquire bitcoins, your wallet provides a unique cryptographic address to the sender. Through its decentralized network and limited number of coins, Bitcoin promises a kind of utopian version of currency.
Proponents say that by getting central banks and governments out of the currency game, the currency will maintain its value better over time. By extricating these entities, some proponents say that Bitcoin returns power to the people. The relative anonymity of Bitcoin is also a huge feature for many. Some proponents such as libertarians like that the government or other authorities cannot easily track who uses the currency. However, such anonymity means that the currency can also be used for criminal activities.
Bitcoin is also popular because the hype surrounding the cryptocurrency has made it a popular trading vehicle. Because the value of the currency fluctuates so much, traders can jump in and make or lose money. This hype and the perceived limited nature of coins has driven the price of bitcoins much higher over the last decade, and it continues to fluctuate significantly. Bitcoin suffers from some significant drawbacks that are intrinsic to its design, notably its limit on the number of coins in circulation and its general volatility.
Big computer miners require a lot of energy to operate. Producing the electricity is expensive and pollutes the environment, for what some detractors say is a currency project with little feasibility. A July study in technology journal Joule showed that mining produced enough carbon emissions to rank it with a small country around the levels of Jordan and Sri Lanka. Researchers from the Massachusetts Institute of Technology and the Technical University of Munich said that Bitcoin mining by itself accounted for 0.
By its very nature, the number of coins is limited, and that poses a serious problem on using it as a currency. In effect, this limit does not allow the money supply to be increased, exposing an economy to destructive deflationary spirals, which were more typical when economies ran on the gold standard. In fact, this concern is a key reason why the gold standard was eliminated.
A challenging situation arises when consumers and others hoard currency during tough economic times.
