Please refer to Affiliate DisclosureBitcoin news About BitcoinWhat Is Bitcoin (BTC)?Bitcoin is a decentralized cryptocurrency originally described in a 2008 whitepaper by a person, or group of people, using the alias Satoshi Nakamoto. It was launched soon after, in January 2009.Bitcoin is a peer-to-peer online currency, meaning that all transactions happen directly between equal, independent network participants, without the need for any intermediary to permit or facilitate them. Bitcoin was created, according to Nakamoto’s own words, to allow “online payments to be sent directly from one party to another without going through a financial institution.”Some concepts for a similar type of a decentralized electronic currency precede BTC, but Bitcoin holds the distinction of being the first-ever cryptocurrency to come into actual use.Who Are the Founders of Bitcoin?Bitcoin’s original inventor is known under a pseudonym, Satoshi Nakamoto. As of 2021, the true identity of the person — or organization — that is behind the alias remains unknown.On October 31, 2008, Nakamoto published Bitcoin’s whitepaper, which described in detail how a peer-to-peer, online currency could be implemented. They proposed to use a decentralized ledger of transactions packaged in batches (called “blocks”) and secured by cryptographic algorithms — the whole system would later be dubbed “blockchain.”Just two months later, on January 3, 2009, Nakamoto mined the first block on the Bitcoin network, known as the genesis block, thus launching the world’s first cryptocurrency. Bitcoin price was $0 when first introduced, and most Bitcoins were obtained via mining, which only required moderately powerful devices (e.g. PCs) and mining software. The first known Bitcoin commercial transaction occurred on May 22, 2010, when programmer Laszlo Hanyecz traded 10,000 Bitcoins for two pizzas. At Bitcoin price today in mid-September 2021, those pizzas would be worth an astonishing $478 million. This event is now known as “Bitcoin Pizza Day.” In July 2010, Bitcoin first started trading, with the Bitcoin price ranging from $0.0008 to $0.08 at that time.However, while Nakamoto was the original inventor of Bitcoin, as well as the author of its very first implementation, he handed the network alert key and control of the code repository to Gavin Andresen, who later became lead developer at the Bitcoin Foundation. Over the years a large number of people have contributed to improving the cryptocurrency’s software by patching vulnerabilities and adding new features.Bitcoin’s source code repository on GitHub lists more than 750 contributors, with some of the key ones being Wladimir J. van der Laan, Marco Falke, Pieter Wuille, Gavin Andresen, Jonas Schnelli and others.What Makes Bitcoin Unique?Bitcoin’s most unique advantage comes from the fact that it was the very first cryptocurrency to appear on the market.It has managed to create a global community and give birth to an entirely new industry of millions of enthusiasts who create, invest in, trade and use Bitcoin and other cryptocurrencies in their everyday lives. The emergence of the first cryptocurrency has created a conceptual and technological basis that subsequently inspired the development of thousands of competing projects.The entire cryptocurrency market — now worth more than $2 trillion — is based on the idea realized by Bitcoin: money that can be sent and received by anyone, anywhere in the world without reliance on trusted intermediaries, such as banks and financial services companies.Thanks to its pioneering nature, BTC remains at the top of this energetic market after over a decade of existence. Even after Bitcoin has lost its undisputed dominance, it remains the largest cryptocurrency, with a market capitalization that surpassed the $1 trillion mark in 2021, after Bitcoin price hit an all-time high of $64,863.10 on April 14, 2021. This is owing in large part to growing institutional interest in Bitcoin, and the ubiquitousness of platforms that provide use-cases for BTC: wallets, exchanges, payment services, online games and more.How Much Bitcoin Is in Circulation?Bitcoin’s total supply is limited by its software and will never exceed 21,000,000 coins. New coins are created during the process known as “mining”: as transactions are relayed across the network, they get picked up by miners and packaged into blocks, which are in turn protected by complex cryptographic calculations.As compensation for spending their computational resources, the miners receive rewards for every block that they successfully add to the blockchain. At the moment of Bitcoin’s launch, the reward was 50 bitcoins per block: this number gets halved with every 210,000 new blocks mined — which takes the network roughly four years. As of 2020, the block reward has been halved three times and comprises 6.25 bitcoins.Bitcoin has not been premined, meaning that no coins have been mined and/or distributed between the founders before it became available to the public. However, during the first few years of BTC’s existence, the competition between miners was relatively low, allowing the earliest network participants to accumulate significant amounts of coins via regular mining: Satoshi Nakamoto alone is believed to own over a million Bitcoin.Mining Bitcoins can be very profitable for miners, depending on the current hash rate and the price of Bitcoin. While the process of mining Bitcoins is complex, we discuss how long it takes to mine one Bitcoin on CoinMarketCap Alexandria — as we wrote above, mining Bitcoin is best understood as how long it takes to mine one block, as opposed to one Bitcoin. As of mid-September 2021, the Bitcoin mining reward is capped to 6.25 BTC after the 2020 halving, which is roughly $299,200 in Bitcoin price today.How Is the Bitcoin Network Secured?Bitcoin is secured with the SHA-256 algorithm, which belongs to the SHA-2 family of hashing algorithms, which is also used by its fork Bitcoin Cash (BCH), as well as several other cryptocurrencies.What Is Bitcoin’s Role as a Store of Value?Bitcoin is the first decentralized, peer-to-peer digital currency. One of its most important functions is that it is used as a decentralized store of value. In other words, it provides for ownership rights as a physical asset or as a unit of account. However, the latter store-of-value function has been debated. Many crypto enthusiasts and economists believe that high-scale adoption of the top currency will lead us to a new modern financial world where transaction amounts will be denominated in smaller units.The smallest units of Bitcoin, 0.00000001 BTC, are called Satoshis (or Sats in short), in a nod to the pseudonymous creator. At Bitcoin price now, 1 Satoshi is equivalent to roughly $0.00048.The top crypto is considered a store of value, like gold, for many — rather than a currency. This idea of the first cryptocurrency as a store of value, instead of a payment method, means that many people buy the crypto and hold onto it long-term (or HODL) rather than spending it on items like you would typically spend a dollar — treating it as digital gold.How Is Bitcoin’s Technology Upgraded?A hard fork is a radical change to the protocol that makes previously invalid blocks/transactions valid, and therefore requires all users to upgrade. For example, if users A and B are disagreeing on whether an incoming transaction is valid, a hard fork could make the transaction valid to users A and B, but not to user C.A hard fork is a protocol upgrade that is not backward compatible. This means every node (computer connected to the Bitcoin network using a client that performs the task of validating and relaying transactions) needs to upgrade before the new blockchain with the hard fork activates and rejects any blocks or transactions from the old blockchain. The old blockchain will continue to exist and will continue to accept transactions, although it may be incompatible with other newer Bitcoin clients.A soft fork is a change to the Bitcoin protocol wherein only previously valid blocks/transactions are made invalid. Since old nodes will recognise the new blocks as valid, a soft fork is backward-compatible. This kind of fork requires only a majority of the miners upgrading to enforce the new rules.Some examples of prominent cryptocurrencies that have undergone hard forks are the following: Bitcoin’s hard fork that resulted in Bitcoin Cash, Ethereum’s hard fork that resulted in Ethereum Classic.Bitcoin Cash has been hard forked since its original forking, with the creation of Bitcoin SV. Read more about the difference between Bitcoin, Bitcoin Cash and Bitcoin SV here.What Is Taproot?Taproot is a soft fork that bundles together BIP 340, 341 and 342 and aims to improve the scalability, efficiency, and privacy of the blockchain by introducing several new features.The two major changes are the introduction of the Merkelized Abstract Syntax Tree (MAST) and Schnorr Signature. MAST introduces a condition allowing the sender and recipient of a transaction to sign off on its settlement together. Schnorr Signature allows users to aggregate several signatures into one for a single transaction. This results in multi-signature transactions looking the same as regular transactions or more complex ones. By introducing this new address type, users can also save on transaction fees, as even complex transactions look like simple, single-signature ones.Although HODLers will probably not notice a big impact, Taproot could become a key milestone to equipping the network with smart contract functionality. In particular, Schnorr Signatures would lay the foundation for more complex applications to be built on top of the existing blockchain, as users start switching to Taproot addresses primarily. If adopted by users, Taproot could, in the long run, result in the network developing its own DeFi ecosystem that rivals those on alternative blockchains like Ethereum.What Is the Lightning Network?The Lightning Network is an off-chain, layered payment protocol that operates bidirectional payment channels which allows instantaneous transfer with instant reconciliation. It enables private, high volume and trustless transactions between any two parties. The Lightning Network scales transaction capacity without incurring the costs associated with transactions and interventions on the underlying blockchain.Who Are the Largest Corporate Holders of Bitcoin?A few years ago, the idea that a publicly traded company might hold Bitcoin on its balance sheets seemed highly laughable. The flagship cryptocurrency was considered to be too volatile to be adopted by any serious business. Many top investors, including Warren Buffett, labeled the asset a “bubble waiting to pop.”This negative sentiment appears to have been broken, with a number of corporate behemoths buying up Bitcoin since 2020. In particular, business intelligence firm MicroStrategy set the pace after it bought $425 million worth of Bitcoin in August and September 2020. Since then, many others have followed suit, including EV manufacturer Tesla.MicroStrategy has by far the largest Bitcoin portfolio held by any publicly-traded company. The business analytics platform has adopted Bitcoin as its primary reserve asset, aggressively buying the cryptocurrency through 2021 and 2022. As of August 30, 2022, the company had 129,699 Bitcoin in its reserve, equivalent to just over $2.5 billion.Other top corporate holders include Marathon Digital Holdings, with 10,054 BTC, Coinbase (9,000), Square Inc. (8,027), and Hut 8 Mining Corp. (7,078).Is Bitcoin Political?Bitcoin is becoming more political by the day, particularly after El Salvador began accepting the currency as legal tender. The country's president, Nayib Bukele, announced and implemented the decision almost unilaterally, dismissing criticism from his citizens, the Bank of England, the IMF, Vitalik Buterin and many others. Since the Bitcoin legal tender law was passed in September 2021, Bukele has also announced plans to build Bitcoin City, a city fully based on mining Bitcoin with geothermal energy from volcanoes.Countries like Mexico, Russia and others have been rumored to be candidates also to accept Bitcoin as legal tender, but thus far, El Salvador stands alone.On the flip side, countries like China have moved to heavily clamp down on Bitcoin mining and trading activities. In May 2021, the Chinese government declared that all crypto-related transactions are illegal. This was followed by a heavy crackdown on Bitcoin mining operations, forcing many crypto-related businesses to flee to friendlier regions.Surprisingly, the anti-crypto stance of the Chinese government has done little to stop the industry. According to data by the University of Cambridge, China is now the second-biggest contributor to Bitcoin's global hash rate, only behind the United States.How Much Is Bitcoin?The current valuation of Bitcoin is constantly moving, all day every day. It is a truly global asset. From a start of under one cent per coin, BTC has risen in price by thousands of percent to the numbers you see above. The prices of all cryptocurrencies are quite volatile, meaning that anyone’s understanding of how much Bitcoin is will change by the minute. However, there are times when different countries and exchanges show different prices and understanding how much Bitcoin is will be a function of a person’s location.Where Can You Buy Bitcoin (BTC)?Bitcoin is, in many regards, almost synonymous with cryptocurrency, which means that you can buy Bitcoin on virtually every crypto exchange — both for fiat money and other cryptocurrencies. Some of the main markets where BTC trading is available are:BinanceCoinbase ProOKExKrakenHuobi GlobalBitfinexIf you are new to crypto, use CoinMarketCap’s own educational portal — Alexandria — to learn how to start buying Bitcoin and other cryptocurrencies.Related Pages:Looking for market and blockchain data for BTC?

When news stories started swirling regarding the possible negative effects of Bitcoin’s energy consumption, many became concerned about Bitcoin and criticized this energy usage. A report found that each Bitcoin transaction takes 1,173 KW hours of electricity, which can “power the typical American home for six weeks.” Another report calculates that the energy required by Bitcoin annually is more than the annual hourly energy usage of Finland, a country with a population of 5.5 million.The news has produced commentary from tech entrepreneurs to environmental activists to political leaders alike. In May 2021, Tesla CEO Elon Musk even stated that Tesla would no longer accept the cryptocurrency as payment, due to his concern regarding its environmental footprint. Though many of these individuals have condemned this issue and move on, some have prompted solutions: how do we make Bitcoin more energy efficient? Others have simply taken the defensive position, stating that the Bitcoin energy problem may be exaggerated.At present, miners are heavily reliant on renewable energy sources, with estimates suggesting that Bitcoin’s use of renewable energy may span anywhere from 40-75%. However, to this point, critics claim that increasing Bitcoin’s renewable energy usage will take away from solar sources powering other sectors and industries like hospitals, factories or homes. The Bitcoin mining community also attests that the expansion of mining can help lead to the construction of new solar and wind farms in the future.Furthermore, some who defend Bitcoin argue that the gold and banking sector — individually — consume twice the amount of energy as Bitcoin, making the criticism of Bitcoin’s energy consumption a nonstarter. Moreover, the energy consumption of Bitcoin can easily be tracked and traced, which the same cannot be said of the other two sectors. Those who defend Bitcoin also note that the complex validation process creates a more secure transaction system, which justifies the energy usage.Another point that Bitcoin proponents make is that the energy usage required by Bitcoin is all-inclusive such that it encompasess the process of creating, securing, using and transporting Bitcoin. Whereas with other financial sectors, this is not the case. For example, when calculating the carbon footprint of a payment processing system like Visa, they fail to calculate the energy required to print money or power ATMs, or smartphones, bank branches, security vehicles, among other components in the payment processing and banking supply chain.What exactly are governments and nonprofits doing to reduce Bitcoin energy consumption? Earlier this year in the U.S., a congressional hearing was held on the topic where politicians and tech figures discussed the future of crypto mining in the U.S, specifically highlighting their concerns regarding fossil fuel consumption. Leaders also discussed the current debate surrounding the coal-to-crypto trend, particularly regarding the number of coal plants in New York and Pennsylvania that are in the process of being repurposed into mining farms.Aside from congressional hearings, there are private sector crypto initiatives dedicated to solving environmental issues such as the Crypto Climate Accord and Bitcoin Mining Council. In fact, the Crypto Climate Accord proposes a plan to eliminate all greenhouse gas emissions by 2040, And, due to the innovative potential of Bitcoin, it is reasonable to believe that such grand plans may be achieved.Crypto WalletsThe most popular wallets for cryptocurrency include both hot and cold wallets. Cryptocurrency wallets vary from hot wallets and cold wallets. Hot wallets are able to be connected to the web, while cold wallets are used for keeping large amounts of coins outside of the internet.Some of the top crypto cold wallets are Trezor, Ledger and CoolBitX. Some of the top crypto hot wallets include Exodus, Electrum and Mycelium.Still not sure of which wallet to use?

Bitcoin (abbreviation: BTC[a]; sign: ₿) is the first decentralized cryptocurrency. Nodes in the peer-to-peer bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight. Consensus between nodes is achieved using a computationally intensive process based on proof of work, called mining, that requires increasing quantities of electricity and guarantees the security of the bitcoin blockchain.[5]

Based on a free market ideology, bitcoin was invented in 2008 by Satoshi Nakamoto, an unknown person.[6] Use of bitcoin as a currency began in 2009,[7] with the release of its open-source implementation.[8]: ch. 1 In 2021, El Salvador adopted it as legal tender.[4] Bitcoin is currently used more as a store of value and less as a medium of exchange or unit of account. It is mostly seen as an investment and has been described by many scholars as an economic bubble.[9] As bitcoin is pseudonymous, its use by criminals has attracted the attention of regulators, leading to its ban by several countries as of 2021[update].[10]

Before bitcoin, several digital cash technologies were released, starting with David Chaum's ecash in the 1980s.[11] The idea that solutions to computational puzzles could have some value was first proposed by cryptographers Cynthia Dwork and Moni Naor in 1992.[11] The concept was independently rediscovered by Adam Back who developed Hashcash, a proof-of-work scheme for spam control in 1997.[11] The first proposals for distributed digital scarcity-based cryptocurrencies came from cypherpunks Wei Dai (b-money) and Nick Szabo (bit gold) in 1998.[12] In 2004, Hal Finney developed the first currency based on reusable proof of work.[13] These various attempts were not successful:[11] Chaum's concept required centralized control and no banks wanted to sign on, Hashcash had no protection against double-spending, while b-money and bit gold were not resistant to Sybil attacks.[11]

2008–2009: Creation

Bitcoin logos made by Satoshi Nakamoto in 2009 (left) and 2010 (right) depict bitcoins as gold tokens.

The domain name bitcoin.org was registered on 18 August 2008.[14] On 31 October 2008, a link to a white paper authored by Satoshi Nakamoto titled Bitcoin: A Peer-to-Peer Electronic Cash System was posted to a cryptography mailing list.[15] Nakamoto implemented the bitcoin software as open-source code and released it in January 2009.[7] Nakamoto's identity remains unknown.[6] All individual components of bitcoin originated in earlier academic literature.[11] Nakamoto's innovation was their complex interplay resulting in the first decentralized, Sybil resistant, Byzantine fault tolerant digital cash system, that would eventually be referred to as the first blockchain.[11][16] Nakamoto's paper was not peer reviewed and was initially ignored by academics, who argued that it could not work, based on theoretical models, even though it was working in practice.[11]

On 3 January 2009, the bitcoin network was created when Nakamoto mined the starting block of the chain, known as the genesis block.[17] Embedded in this block was the text "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks", which is the date and headline of an issue of The Times newspaper.[7] Nine days later, Hal Finney received the first bitcoin transaction: ten bitcoins from Nakamoto.[18] Wei Dai and Nick Szabo were also early supporters.[17] In 2010, the first known commercial transaction using bitcoin occurred when programmer Laszlo Hanyecz bought two Papa John's pizzas for ₿10,000.[19]

2010–2012: Early growth

Blockchain analysts estimate that Nakamoto had mined about one million bitcoins[20] before disappearing in 2010 when he handed the network alert key and control of the code repository over to Gavin Andresen. Andresen later became lead developer at the Bitcoin Foundation,[21][22] an organization founded in September 2012 to promote bitcoin.[23]

After early "proof-of-concept" transactions, the first major users of bitcoin were black markets, such as the dark web Silk Road. During its 30 months of existence, beginning in February 2011, Silk Road exclusively accepted bitcoins as payment, transacting ₿9.9 million, worth about $214 million.[24]: 222

2013–2014: First regulatory actions

In March 2013, the US Financial Crimes Enforcement Network (FinCEN) established regulatory guidelines for "decentralized virtual currencies" such as bitcoin, classifying American bitcoin miners who sell their generated bitcoins as money services businesses, subject to registration and other legal obligations.[25] In May 2013, US authorities seized the unregistered exchange Mt. Gox.[26] In June 2013, the US Drug Enforcement Administration seized ₿11.02 from a man attempting to use them to buy illegal substances. This marked the first time a government agency had seized bitcoins.[27] The FBI seized about ₿30,000 in October 2013 from Silk Road, following the arrest of its founder Ross Ulbricht.[28]

In December 2013, the People's Bank of China prohibited Chinese financial institutions from using bitcoin.[29] After the announcement, the value of bitcoin dropped,[30] and Baidu no longer accepted bitcoins for certain services.[31] Buying real-world goods with any virtual currency had been illegal in China since at least 2009.[32]

2015–2019

Research produced by the University of Cambridge estimated that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.[33] In August 2017, the SegWit software upgrade was activated. Segwit was intended to support the Lightning Network as well as improve scalability.[34] SegWit opponents, who supported larger blocks as a scalability solution, forked to create Bitcoin Cash, one of many forks of bitcoin.[35]

In December 2017, the first futures on bitcoin was introduced by the CME.[36]

In February 2018, price crashed after China imposed a complete ban on Bitcoin trading.[37] The percentage of bitcoin trading in the Chinese renminbi fell from over 90% in September 2017 to less than 1% in June 2018.[38] During the same year, Bitcoin prices were negatively affected by several hacks or thefts from cryptocurrency exchanges.[39]

2020–present

Bitcoin price in US dollars

In 2020, some major companies and institutions started to acquire bitcoin: MicroStrategy invested $250 million in bitcoin as a treasury reserve asset,[40] Square, Inc., $50 million,[41] and MassMutual, $100 million.[42] In November 2020, PayPal added support for bitcoin in the US.[43]

In February 2021, Bitcoin's market capitalization reached $1 trillion for the first time.[44] In November 2021, the Taproot soft-fork upgrade was activated, adding support for Schnorr signatures, improved functionality of smart contracts and Lightning Network.[45] Before, Bitcoin only used a custom elliptic curve with the ECDSA algorithm to produce signatures.[46]: 101 In September 2021, Bitcoin became legal tender in El Salvador, alongside the US dollar.[4] In October 2021, the first bitcoin futures ETF, called BITO, from ProShares was approved by the SEC and listed on the Chicago Mercantile Exchange.[47]

In May and June 2022, the bitcoin price fell following the collapses of TerraUSD, a stablecoin,[48] and the Celsius Network, a cryptocurrency loan company.[49][50]

In 2023, ordinals, non-fungible tokens (NFTs) on Bitcoin, went live.[51] In January 2024, the first 11 US spot bitcoin exchange-traded funds (ETFs) began trading, offering direct exposure to bitcoin for the first time on American stock exchanges.[52][53]

Units and divisibility

The unit of account of the bitcoin system is the bitcoin. It is most commonly represented with the currency code BTC[a] as well as the symbol ₿.[1] XBT, a code that conforms to ISO 4217 though not officially part of it, is used by Bloomberg L.P.[54]

No uniform capitalization convention exists; some sources use Bitcoin, capitalized, to refer to the technology and network, and bitcoin, lowercase, for the unit of account.[55] The Oxford English Dictionary advocates the use of lowercase bitcoin in all cases.[56]

One bitcoin is divisible to eight decimal places.[8]: ch. 5 Units for smaller amounts of bitcoin are the millibitcoin (mBTC), equal to 1⁄1000 bitcoin, and the satoshi[b] (sat), representing 1⁄100000000 (one hundred millionth) bitcoin, the smallest amount possible.[2] 100,000 satoshis are one mBTC.[57]

Blockchain

Further information: Blockchain § Structure and design

As a decentralized system, bitcoin operates without a central authority or single administrator,[58] so that anyone can create a new bitcoin address and transact without needing any approval.[8]: ch. 1 This is accomplished through a specialized distributed ledger called a blockchain that records bitcoin transactions.[59]

The blockchain is implemented as an ordered list of blocks. Each block contains a SHA-256 hash of the previous block,[59] "chaining" them in chronological order.[8]: ch. 7 [59] The blockchain is maintained by a peer-to-peer network.[24]: 215–219 Individual blocks, public addresses, and transactions within blocks are public information, and can be examined using a blockchain explorer.[60]

Nodes validate and broadcast transactions, each maintaining a copy of the blockchain for ownership verification.[61] A new block is created every 10 minutes on average, updating the blockchain across all nodes without central oversight. This process tracks bitcoin spending, ensuring each bitcoin is spent only once. Unlike a traditional ledger that tracks physical currency, bitcoins exist digitally as unspent outputs of transactions.[8]: ch. 5

Addresses and transactions

Simplified chain of ownership. In practice, a transaction can have more than one input and more than one output.[62]

In the blockchain, bitcoins are linked to specific addresses that are hashes of a public key. Creating an address involves generating a random private key and then computing the corresponding address. This process is almost instant, but the reverse (finding the private key for a given address) is nearly impossible.[8]: ch. 4 Publishing a bitcoin address does not risk its private key, and it is extremely unlikely to accidentally generate a used key with funds. To use bitcoins, owners need their private key to digitally sign transactions, which are verified by the network using the public key, keeping the private key secret.[8]: ch. 5

Bitcoin transactions use a Forth-like scripting language,[8]: ch. 5 involving one or more inputs and outputs. When sending bitcoins, a user specifies the recipients' addresses and the amount for each output. This allows sending bitcoins to several recipients in a single transaction. To prevent double-spending, each input must refer to a previous unspent output in the blockchain.[62] Using multiple inputs is similar to using multiple coins in a cash transaction. As in a cash transaction, the sum of inputs can exceed the intended sum of payments. In such a case, an additional output can return the change back to the payer.[62] Unallocated input satoshis in the transaction become the transaction fee.[62]

Losing a private key means losing access to the bitcoins, with no other proof of ownership accepted by the protocol.[24] For instance, in 2013, a user lost ₿7,500, valued at US$7.5 million, by accidentally discarding a hard drive with the private key.[63] It is estimated that around 20% of all bitcoins are lost.[64] The private key must also be kept secret as its exposure, such as through a data breach, can lead to theft of the associated bitcoins.[8]: ch. 10 [65] As of December 2017[update], approximately ₿980,000 had been stolen from cryptocurrency exchanges.[66]

So far this year, Bitcoin has a change of 57.82%. Bitcoin is classified as a Currency under CoinDesks Digital Asset Classification Standard (DACS).Bitcoin is the world’s first decentralized cryptocurrency – a type of digital asset that uses public-key cryptography to record, sign and send transactions over the Bitcoin blockchain – all done without the oversight of a central authority.The Bitcoin network (with an upper-case “B”) was launched in January 2009 by an anonymous computer programmer or group of programmers under the pseudonym “Satoshi Nakamoto.” The network is a peer-to-peer electronic payment system that uses a cryptocurrency called bitcoin (lower case “b”) to transfer value over the internet or act as a store of value like gold and silver.Each bitcoin is made up of 100 million satoshis (the smallest units of bitcoin), making individual bitcoin divisible up to eight decimal places. That means anyone can purchase a fraction of a bitcoin with as little as one U.S. dollar.Bitcoin priceBitcoin’s price is renowned for being highly volatile, but despite that, it has become the top performing asset of any class (including stocks, commodities and bonds) over the past decade – climbing a staggering 9,000,000% between 2010 and 2020.When the cryptocurrency was launched at the beginning of 2009, as Satoshi Nakamoto mined the bitcoin genesis block (the first-ever block on the Bitcoin blockchain), 50 BTC entered circulation at a price of $0.00.Fifty bitcoin continued to enter circulation every block (created once every 10 minutes) until the first halving event took place in November 2012 (see below). Halvings refer to bitcoin’s issuance system, which was programmed into Bitcoin’s code by Satoshi Nakamoto. It essentially involves automatically halving the number of new BTC entering circulation every 210,000 blocks.In February 2011, BTC’s price reached parity with the U.S dollar for the first time. The milestone encouraged new investors into the market, and over the next four months, bitcoin’s price continued to rise – peaking at over $30.By early 2013, the leading cryptocurrency had recovered from a prolonged bearish episode and rose above $1,000, albeit only briefly. But with the infamous Mt Gox hack, China announcing its first ban on crypto and other situations, it took a further four years for the BTC price to return to above $1,000 again. Once that level was passed, however, bitcoin’s price continued to surge dramatically throughout 2017 until BTC peaked at its previous long-standing all-time high of $19,850.Over 2018, the entire crypto market plunged into what is now known as the “crypto winter” – a yearlong bear market. It wasn’t until December 2020, when bitcoin returned to test the previous all-time high, that it eventually surpassed that historical level and rose a further 239% over the next 119 days to a new all-time high of $64,799.What is Bitcoin?Bitcoin is the world’s first decentralized cryptocurrency – a type of digital asset that uses public-key cryptography to record, sign and send transactions over the Bitcoin blockchain – all done without the oversight of a central authority. It was launched in January 2009 by an anonymous computer programmer or group of programmers under the pseudonym 'Satoshi Nakamoto'.How does Bitcoin work?Bitcoin and other cryptocurrencies are like the email of the financial world. The currency doesn’t exist in a physical form, and the coin is transacted directly between the sender and the receiver without banking intermediaries to facilitate the transaction. Everything is done publicly through a transparent, immutable, distributed ledger technology called blockchain.Here are the main features of blockchain technology:Bitcoin transactions are recorded on a public, distributed ledger known as a “blockchain” that anyone can download and help maintain.Transactions are sent directly from the sender to the receiver without any intermediaries.Holders who store their own bitcoin have complete control over it. It cannot be accessed without the holder’s cryptographic key.Bitcoin doesn’t exist in a physical form.Bitcoin has a fixed supply of 21 million. No more bitcoin can be created and units of bitcoin cannot be destroyed.Bitcoin users send and receive coins over the network by inputting the public-key information attached to each person’s digital wallet.In order to incentivize the distributed network of people verifying bitcoin transactions (miners), a fee is attached to each transaction. The fee is awarded to whichever miner adds the transaction to a new block. Fees work on a first-price auction system, where the higher the fee attached to the transaction, the more likely a miner will process that transaction first.Every single bitcoin transaction that takes place has to be permanently committed to the Bitcoin blockchain ledger through a process called “mining.” Bitcoin mining refers to the process where miners compete using specialized computer equipment known as application-specific integrated circuit (ASIC) chips to unlock the next block in the chain.Unlocking blocks work as follows:Crypto mining uses a system called cryptographic hashing. This function simply takes any input (messages, words or data of any kind) and turns it into a fixed-length alphanumeric code known as a “hash.”Each input creates a completely unique hash, and it’s almost impossible to predict what inputs will create certain hashes. Even changing one character of the input will result in a totally different fixed-length code.Each new block has a value called a “target hash.” In order to win the right to fill the next block, miners need to produce a hash that is lower than or equal to the numeric value of the ‘target’ hash. Since hashes are completely random, it’s just a matter of trial and error until one miner is successful.This method of requiring miners to use machines and spend time and energy trying to achieve something is known as a proof-of-work system and is designed to deter malicious agents from spamming or disrupting the network.Whoever successfully unlocks the next block is rewarded with a set number of bitcoin known as “block rewards” and gets to add a number of transactions to the new block. They also earn any transaction fees attached to the transactions they add to the new block. A new block is discovered roughly once every 10 minutes.Bitcoin block rewards decrease over time. Every 210,000 blocks, or about once every four years, the number of bitcoin received from each block reward is halved to gradually reduce the number of bitcoin entering the space over time. As of 2021, miners receive 6.25 bitcoins each time they mine a new block. The next bitcoin halving is expected to occur in 2024 and will see bitcoin block rewards drop to 3.125 bitcoins per block. As the supply of new bitcoin entering the market gets smaller, it will make buying bitcoin more competitive – assuming demand for bitcoin remains high.Who created Bitcoin?The creator of Bitcoin, known only by the pseudonym "Satoshi Nakamoto," first proposed this revolutionary digital currency in a 2008 whitepaper titled "Bitcoin: A Peer-to-Peer Electronic Cash System." Satoshi devised Bitcoin as a decentralized, peer-to-peer network, able to facilitate financial transactions without a central authority like a government or bank. In doing so, Satoshi solved a key issue, the double-spending problem, by creating a proof-of-work consensus mechanism within a blockchain structure. Bitcoin's network was activated in January 2009 when Satoshi mined the first block, or the "genesis block." Despite the transformative impact of Bitcoin, Satoshi Nakamoto's identity remains shrouded in mystery, a symbol of the privacy-oriented ethos at the heart of the cryptocurrency movement.Bitcoin’s energy consumptionThe process of requiring network contributors to dedicate time and resources to creating new blocks ensures the network remains secure. But that security comes at a price. As of 2021, the Bitcoin network consumes about 93 terawatt hours (TWh) of electricity per year – around the same energy consumed by the 34th-largest country in the world.This appetite for electricity has drawn widespread criticism from celebrities such as Tesla CEO Elon Musk to government bodies such as China’s State Council and the U.S. Senate over Bitcoin’s impact on climate change. But while the electricity figures are alarmingly high, it’s important to note that bitcoin mining at most accounts for 1.29% of any single country’s energy consumption. Not to mention, Bitcoin is a complete financial system whose energy consumption can be measured and tracked, unlike the fiat system, which cannot be accurately measured and requires a range of additional layers to function, including ATMs, card machines, bank branches, security vehicles, storage facilities and huge data centers.There are also a number of initiatives including the Crypto Climate Accord and the Bitcoin Mining Council that aim to improve Bitcoin’s carbon footprint by encouraging miners to use renewable sources of energy.ManagementAs already mentioned, the Bitcoin network was created by a pseudonymous programmer, or group of programmers, known only as “Satoshi Nakamoto.” During its early development, other developers joined to work on the protocol, including cypherpunk Hal Finney, cryptographers Wei Dai and Nick Szabo and software developer Gavin Andresen.There were also a range of other developers including Pieter Wuille and Peter Todd who contributed to the development of Bitcoin Core – the first client on the Bitcoin network. A client is a piece of software that enables a network participant to run a node and connect to the blockchain.An American nonprofit called the Bitcoin Foundation was founded in 2012 to support the development and adoption of the Bitcoin protocol. After three years, however, the foundation eventually ran out of cash and was dissolved.In 2014, Adam Back, another cypherpunk and the inventor of Hashcash – a cryptographic hashing algorithm created in 1997 which used the same proof-of-work mechanism that Bitcoin would later adopt – co-founded Blockstream. Blockstream is a for-profit tech company that develops new infrastructure on the Bitcoin network, including Lightning Network and sidechains.Read less...Buy crypto on a secure, trusted platform.Cryptoasset investing is highly volatile and unregulated in some EU countries.

How does Bitcoin work?

This is a question often surrounded by confusion, so here's a quick explanation!

The basics for a new user

As a new user, you can get started with Bitcoin without understanding the technical details. Once you've installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should be used only once.

Balances - block chain

The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. It allows Bitcoin wallets to calculate their spendable balance so that new transactions can be verified thereby ensuring they're actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography.

Transactions - private keys

A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast to the network and usually begin to be confirmed within 10-20 minutes, through a process called mining.

Processing - mining

Mining is a distributed consensus system that is used to confirm pending transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all the subsequent blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively to the block chain. In this way, no group or individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.

Going down the rabbit hole

This is just a short summary of Bitcoin. If you want to learn more of the details, you can read the original paper that describes its design, the developer documentation, or explore the Bitcoin wiki.

Bitcoin is designed to be completely decentralized and not controlled by any single authority. With a total supply of 21 million, its scarcity and decentralized nature make it almost impossible to inflate or manipulate. For this reason, many consider bitcoin to be the ultimate store of value or ‘Digital Gold’. Bitcoin is fully open-source and operates on a proof-of-work blockchain, a shared public ledger and history of transactions organized into "blocks" that are "chained" together to prevent tampering. This technology creates a permanent record of each transaction. Users on the Bitcoin network verify transactions through a process known as mining, which is designed to confirm new transactions are consistent with older transactions that have been confirmed in the past, ensuring users can not spend a Bitcoin they don’t have or attempt to double-spend coins.BTC in practice New coins are created as part of the Bitcoin mining process. Bitcoins are rewarded to miners who operate computer systems that help to secure the network and validate incoming transactions. These Bitcoin miners run full nodes and use specialized hardware otherwise known as Application Specific Integrated Circuit Chips (ASICs) to find and generate new blocks. Once a series of computationally demanding problems have been solved a completed "block" is added to the ever-growing "chain", this mining process can fluctuate and become easier or harder depending on network demand and value, this is known as the network difficulty. Besides block rewards, miners also collect transaction fees which further incentivizes them to secure the network and verify transactions. This independent network of miners also decreases the chance for fraud or false information to be recorded, as the majority of miners need to confirm the authenticity of each block of data before it's added to the blockchain, in a process known as "proof of work."Project LinksWebsiteBitcoin.orgDocumentsWhitepaper Please verify all project links, data may change over time.

Nodes in the peer-to-peer bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight. Consensus between nodes is achieved using a computationally intensive process based on proof of work, called mining, that requires increasing quantities of electricity and guarantees the security of the bitcoin blockchain.

Based on a free market ideology, bitcoin was invented in 2008 by Satoshi Nakamoto, an unknown person. Use of bitcoin as a currency began in 2009, with the release of its open-source implementation. In 2021, El Salvador adopted it as legal tender. Bitcoin is currently used more as a store of value and less as a medium of exchange or unit of account. It is mostly seen as an investment and has been described by many scholars as an economic bubble. As bitcoin is pseudonymous, its use by criminals has attracted the attention of regulators, leading to its ban by several countries as of 2021. WikipediaAbout United States DollarThe United States dollar is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.

The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank.

The U.S. dollar was originally defined under a bimetallic standard of 371.25 grains fine silver or, from 1837, 23.22 grains fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. Since 1971, all links to gold have been repealed.

The U.S. dollar became an important international reserve currency after the First World War, and displaced the pound sterling as the world's primary reserve currency by the Bretton Woods Agreement towards the end of the Second World War.
