Welcome to the 32nd Coin Report. In today’s report, I will be assessing the fundamental and technical strengths and weaknesses of ExchangeCoin. This will be comprised of an analysis of a number of significant metrics, an evaluation of the project’s community and development and an overview of its price-history. The report will conclude with a grading out of 10. ExchangeCoin was launched in November 2017 with an ICO that raised 650 BTC, equating to over $5,000,000 at the time. The token issued, EXCC, has a maximum supply of 32,003,133, with 4mn EXCC sold during the ICO. Further, the project also has a premine of 12.1mn EXCC, equating to 37.95% of the maximum supply (from which the 4mn was sold to the public in the token sale). The token itself operates on the Equihash algorithm, and underwent a hard fork in July 2018, after which the network migrated to a dual Proof-of-Work/Proof-of-Stake consensus mechanism, with 30% of block rewards rewarded to stakers and 70% to miners. The block reward is progressively diminishing, with the current reward at 24.5 EXCC per block, with 2.5-minute block times.
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]

Почему Bitcoin актив

На специальном кошельке. У каждого из них есть публичный адрес и приватный ключ. Создатели криптовалют придумали интересную схему безопасности — для каждой операции кошелек создает новые уникальные адреса. Допустим, вы захотели перевести коины, которые лежат на кошельке А. Кошелек сначала сам создаст второй кошелек В, а потом отправит деньги на нужный адрес. Чтобы принять транзакцию создается кошелек С, из которого деньги автоматически отправляются на кошелек А. Таким образом, никто не узнает настоящий адрес кошелька, на котором хранятся деньги.
Если предельно всё упростить, то объяснить феномен биткоинов можно на примере крышечек от лимонада (да, привет фанатам Fallout). Допустим, подделать эти крышечки нельзя, пробежаться по магазинам и скупить весь лимонад тоже: он больше не производится. Количество крышек ограниченно и заранее известно, так что надо просто бродить и смотреть под ноги — вдруг наткнётесь на крышечку.

Где я могу купить Bitcoin наличные деньги

Transactions are defined using a Forth-like scripting language.[7]:ch. 5 Transactions consist of one or more inputs and one or more outputs. When a user sends bitcoins, the user designates each address and the amount of bitcoin being sent to that address in an output. To prevent double spending, each input must refer to a previous unspent output in the blockchain.[82] The use of multiple inputs corresponds to the use of multiple coins in a cash transaction. Since transactions can have multiple outputs, users can send bitcoins to multiple recipients in one transaction. As in a cash transaction, the sum of inputs (coins used to pay) can exceed the intended sum of payments. In such a case, an additional output is used, returning the change back to the payer.[82] Any input satoshis not accounted for in the transaction outputs become the transaction fee.[82]

Сообщество Ethereum обсуждало, следует ли вернуть эфир инвесторам и каким именно способом осуществить возврат, а разработчики The DAO из Германии пытались ответно атаковать хакера[33], поскольку децентрализованный характер The DAO и Ethereum означают отсутствие центрального органа, который мог бы предпринять быстрое действие, и требуют согласия пользователей[31]. После обсуждения в течение нескольких недель 20 июля 2016 года над проектом Ethereum был произведён хардфорк[34] (развилка цепочки блоков, а не программного кода), чтобы отменить взлом и вернуть инвесторам средства, похищенные у The DAO[35]. Это было первое ответвление цепочки блоков с целью возвращения похищенных средств инвесторам[36].
Нестабильность курса – это один из недостатков криптовалют и причина недоверия к ним. А какие другие есть минусы у цифровой валюты? Например, регулирование. Изначально BTC была полностью децентрализованной и независимой валютой. Это означало, что участник сети в США и участник сети в Буркина-Фасо равны. Однако все больше стран задумываются о регулировании криптовалюты. А в некоторых частях мира (Боливия, Индонезия, Таиланд) она запрещена.
Bitcoin, along with other cryptocurrencies, has been described as an economic bubble by at least eight Nobel Memorial Prize in Economic Sciences laureates, including Robert Shiller,[145] Joseph Stiglitz,[204] and Richard Thaler.[205][206] Noted Keynesian economist Paul Krugman has described bitcoin as "a bubble wrapped in techno-mysticism inside a cocoon of libertarian ideology",[136] professor Nouriel Roubini of New York University has called bitcoin the "mother of all bubbles",[207] and University of Chicago economist James Heckman has compared it to the 17th-century tulip mania.[206] Former Federal Reserve Chairman Alan Greenspan has also described bitcoin as a "bubble";[208] the investors Warren Buffett and George Soros have respectively characterized it as a "mirage"[209] and a "bubble";[210] while the business executives Jack Ma and Jamie Dimon have called it a "bubble"[211] and a "fraud",[212] respectively.
Во-вторых, блокчейн. Это то, чего нет ни у одной другой платежной системы. Блокчейн универсален, надежен, децентрализован. При этом гарантирует анонимность и высокую скорость транзакций. И применяется он в разных сферах. Начиная от финансового сектора, завершая альтернативной энергетикой. Это очевидные преимущества, которые определяют ценность криптовалют.

The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and the media.[228] In the United States, the FBI prepared an intelligence assessment,[229] the SEC issued a pointed warning about investment schemes using virtual currencies,[228] and the U.S. Senate held a hearing on virtual currencies in November 2013.[230] The U.S. government claimed that bitcoin was used to facilitate payments related to Russian interference in the 2016 United States elections.[231]
