У 2018 році австралійське місто Агнес Вотерс стало першим містом у світі, де приймають криптовалюту.[19] У місті можна розплатитися біт­ко­їнами (Bitcoin), Bitcoin Cash (Bitcoin.​Cash), ефіром (ETH/USD), лайт­коїнами (LTC/USD) і NEM.[20] Також у співпраці із керівництвом Французької Полінезії громадська організація, що складається з благодійників, науковців та інвесторів, працює над створенням альтернативи сучасним країнам — проекту «Плавучий острів» (Floating Island Project). Ця програма передбачає створення штучного острова, де розташовуватимуться будинки для 300 жителів. Утворення матиме власний уряд, а місцевими грошима буде криптовалюта Varyon.[21]
Криптографія з метою конфіденційних платежів почала використовуватися з 1990 року в системі DigiCash Девіда Чома, компанія якого збанкрутувала в 1998 році[14]. Однак, його платіжна система була централізованою, а вперше термін «криптовалюта» почав використовуватися після появи пірингової платіжної системи Bitcoin, яка була розроблена в 2009 році людиною або групою осіб під псевдонімом Сатосі Накамото[15] і використовує хешування SHA-256 і систему proof-of-work[16].

The U.S. federal investigation was prompted by concerns of possible manipulation during futures settlement dates. The final settlement price of CME bitcoin futures is determined by prices on four exchanges, Bitstamp, Coinbase, itBit and Kraken. Following the first delivery date in January 2018, 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.[192][193]

In March 2013 the blockchain temporarily split into two independent chains with different rules due to a bug in version 0.8 of the bitcoin software. The two blockchains operated simultaneously for six hours, each with its own version of the transaction history from the moment of the split. Normal operation was restored when the majority of the network downgraded to version 0.7 of the bitcoin software, selecting the backward compatible version of the blockchain. As a result, this blockchain became the longest chain and could be accepted by all participants, regardless of their bitcoin software version.[42] During the split, the Mt. Gox exchange briefly halted bitcoin deposits and the price dropped by 23% to $37[42][43] before recovering to previous level of approximately $48 in the following hours.[44] 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 Service Businesses (MSBs), that are subject to registration or other legal obligations.[45][46][47] In April, exchanges BitInstant and Mt. Gox experienced processing delays due to insufficient capacity[48] resulting in the bitcoin price dropping from $266 to $76 before returning to $160 within six hours.[49] The bitcoin price rose to $259 on 10 April, but then crashed by 83% to $45 over the next three days.[40] On 15 May 2013, US authorities seized accounts associated with Mt. Gox after discovering it had not registered as a money transmitter with FinCEN in the US.[50][51] On 23 June 2013, the US Drug Enforcement Administration listed ₿11.02 as a seized asset in a United States Department of Justice seizure notice pursuant to 21 U.S.C. § 881.[52][better source needed] This marked the first time a government agency had seized bitcoin.[53] The FBI seized about ₿30,000[54] in October 2013 from the dark web website Silk Road during the arrest of Ross William Ulbricht.[55][56][57] These bitcoins were sold at blind auction by the United States Marshals Service to venture capital investor Tim Draper.[54] Bitcoin's price rose to $755 on 19 November and crashed by 50% to $378 the same day. On 30 November 2013 the price reached $1,163 before starting a long-term crash, declining by 87% to $152 in January 2015.[40] On 5 December 2013, the People's Bank of China prohibited Chinese financial institutions from using bitcoins.[58] After the announcement, the value of bitcoins dropped,[59] and Baidu no longer accepted bitcoins for certain services.[60] Buying real-world goods with any virtual currency had been illegal in China since at least 2009.[61]
Отсутствие контроля за сетью. Так как блокчейн — распределённая база, созданная на основе равноправных узлов, сеть Биткойн не имеет контролирующего центра, который может заморозить какой-либо счёт, изменить количество денежных единиц в системе, заблокировать либо отменить платёж. Есть небольшие комиссионные, размер которых на практике почти неощутим и не зависит от суммы перевода. Сделки в системе являются безвозвратными так же, как и операции с наличными деньгами.

Bitcoin (BTC) is known as the first open-source, peer-to-peer, digital cryptocurrency that was developed and released by a group of unknown independent programmers named Satoshi Nakamoto in 2008. Cryptocoin doesn’t have any centralized server used for its issuing, transactions and storing, as it uses a distributed network public database technology named blockchain, which requires an electronic signature and is supported by a proof-of-work protocol to provide the security and legitimacy of money transactions. The issuing of Bitcoin is done by users with mining capabilities and is limited to 21 million coins. Currently, Bitcoin’s market cap surpasses $138 billion and this is the most popular kind of digital currency. Buying and selling cryptocurrency is available through special Bitcoin exchange platforms or ATMs.
Появление криптовалюты — следующий шаг в развитии экономики. Монеты и бумажки — это прошлый век. Их не всегда удобно использовать: с собой можно носить ограниченное количество, самостоятельно отсчитывать и проверять сдачу, их можно потерять или испортить. Электронные деньги — эквивалент бумажных, только управлять ими удобней. С точки зрения государства и бизнеса безналичные расчеты тоже удобны — электронные платежи проходят быстро, дешево, безопасно.

ICO является нерегулируемым средством, с помощью которого привлекаются средства для нового предприятия в форме криптовалюты. ICO используется стартапами для обхода строгих и регулируемых процессов привлечения капитала, необходимых венчурным предпринимателям или банкам.

In May of 2017, the world’s first ‘Lightning Network’ transaction took place using Litecoin, where 0.00000001 LTC was transferred from Zurich to San Francisco in less than one second. The open-source Litecoin software can be downloaded, used, modified and distributed by individuals without fear of corruption, as the independent verification of source code and binaries makes for a completely transparent process.
