Satoshi Nakamoto is the pseudonym of bitcoin's creator. Nakamoto's true identity has never been confirmed, though some have claimed to be Nakamoto. Others have been accused of being the "real" Nakamoto. Neither Nakamoto's gender, nor whether he or she is a single person or a group of people, has ever been conclusively established.
Until 2010, Nakamoto collaborated with an initially small community via mailing lists. Though the team was open-sourced, Nakamoto took care never to reveal anything personal, cementing the ambiguity surrounding Nakamoto's identity. Nakamoto did once state that his/her birth date was April 5, 1975, though some theorize that this was meant to be deliberately misleading, or possibly symbolic (April 5 was the date in 1933 that President Franklin D. Roosevelt signed an executive order forbidding the hoarding of precious commodities like gold, while 1975 was the year in which ownership of gold by U.S. citizens was made legal again). Eventually, Nakamoto faded from the community.
Though the bitcoin and blockchain development team was open-sourced, Nakamoto took care never to reveal anything personal, adding to the ambiguity surrounding his identity.
On April 26 2011, Nakamoto sent one final communication to the team stating simply that Nakamoto had "moved on to other projects."
Gavin Andresen, a professor at the University of Massachusetts who worked closely with Nakamoto, remarked that he had a constant sense that Nakamoto was wary of giving out even the subtlest details about his personal identity in the 2014 documentary, "The Rise and Rise of Bitcoin." In the documentary, he said of Nakamoto, “He was so worried about people finding out who he was...I don’t know why. My last email to him was telling him I’d agreed to go visit the folks over at the CIA [laughs]. Whether that had something to do with him deciding to cut off...he had been pulling away before then.”
Although many have been accused of being the true Nakamoto Nakamoto, none of those accusations has ever been confirmed. Some popular theories posit that Nakamoto's true identity is either Hal Finney, Nick Szabo or Wei Dai - the latter two of whom are credited with inventing concepts that served as precursors to bitcoin. Hal Finney is the first-ever recipient of a bitcoin transaction, which he allegedly received from Nakamoto himself. He had also met with both Szabo and Wei Dai during the development of bitcoin.
An article in Newsweek in 2014 alleged that a Southern California man named Dorian Satoshi Nakamoto was bitcoin's mysterious founder, but he denied having anything to do with bitcoin, claiming he hadn't even heard of it until about three weeks before the allegations began. In the midst of the resulting media frenzy, Nakamoto's long-dormant bitcoin foundation account briefly returned to life to publicly post the sentence, "I am not Dorian Nakamoto." This was met with mixed reception, some saying that it proved Dorian Nakamoto's lack of affiliation with bitcoin, while one man tweeted, "Then again...isn't that what Dorian Nakamoto WOULD say (if he was the real Satoshi Nakamoto)?"
In May of 2016, an Australian entrepreneur named Craig Wright publicly identified himself as the bitcoin creator Nakamoto. As proof, he showed fellow bitcoin developer Gavin Andresen that he had digitally signed messages using cryptographic keys created during the early days of bitcoin's development and linked to blocks of bitcoins known to have been mined by Nakamoto. However, The Economist and others were skeptical.
Some believe that David Kleiman, a computer expert with known affiliations with Hal Finney, may have been Nakamoto, or one of the people using the Nakamoto persona. Kleiman passed away in 2013. In 2018 Wright was sued for $10 billion by the family of Kleiman, his deceased former colleague, for wrongfully obtaining a massive amount of bitcoin from Kleiman following his death in 2013.
On June 29, 2018, an individual claiming to be Nakamoto made a post on a website called nakamotofamilyfoundation.org about a book he had begun writing. In one of the excerpts on the site, the author asserted that Nakamoto is not a "real" name: "specifically," he wrote, "not a legal name." The author said that the name is "primarily the essence of thoughts and reason." The author also said he chose "Satoshi Nakamoto" because the commonality of the name in Japanese is similar to a name like "John Smith" in English. The excerpts also include nearly a full page dedicated to Hal Finney.
On November 29th, 2018, Nakamoto's original profile on the website P2Pfoundation.ning.com made a post with a single word, "nour." No further explanation or follow-up was posted to the profile, though some speculated that since the word means "light" in Arabic, Hebrew, and Aramaic, this had something to do with Nakamoto's intended, cryptic message. Others speculated that Nakamoto's account had been hacked, and the post was simply nonsense made by an unauthorized user. Earlier that day, Nakamoto's activity feed indicated that the profile had accepted a new friend account for the first time in years. The account that was added by Nakamoto belonged to Brazilian citizen Wagner Tamanaha, who tweeted in Portuguese after these posts were made that he was "under investigation."
Whitepaper copyright claims
In April 2019, Craig Wright applied for registrations with the United States Copyright Office, claiming authorship of bitcoin's original whitepaper, “Bitcoin: A Peer-to-Peer Electronic Cash System.” On May 22, 2019, a day after the news broke, the U.S. Copyright Office published a statement: “As a general rule, when the Copyright Office receives an application for registration, the claimant certifies as to the truth of the statements made in the submitted materials. The Copyright Office does not investigate the truth of any statement made...In a case in which a work is registered under a pseudonym, the Copyright Office does not investigate whether there is a provable connection between the claimant and the pseudonymous author.”
On May 24, 2019, the CEO of a Chinese cryptocurrency market research firm, Wei Liu, registered a copyright for bitcoin's whitepaper, making him the second person to do so. Although he did not confirm whether or not he was Nakamoto, he told Coindesk, "I filed it just to let people know anyone can register a copyright. Everyone can be Satoshi Nakamoto. Wright responded over Twitter with the message, "Now we can both show our credentials and see who ends up wearing an orange suit!"
Whale Alert analysis
In July 2020, the blockchain analysis firm Whale Alert published a report saying that Nakamoto had continued to mine bitcoin longer than had previously been thought. Whale Alert said that patterns in mining data indicated that Nakamoto had kept mining in order to help stabilize the nascent blockchain. The company calculated that Nakamoto had mined more than 1 million bitcoin.
Bitcoin (BTC) is a digital asset (or cryptocurrency) and payment system run by a huge, global, decentralized peer-to-peer network of computers. Bitcoin was created in 2009 by a programmer or group of programmers under the pseudonym Satoshi Nakamoto.
Bitcoin is the world's first cryptocurrency. It is essentially a software program that slowly releases new bitcoins into a network of computers running the software. These "coins" are awarded to computers that successfully verify transactions made between users before the rest of the network. This process is referred to as "mining" bitcoin. The program is designed such that coins become more and more difficult to mine as time passes. As of February 2018, approximately 80% of all bitcoins have been mined. The limit of 21 million bitcoins is expected to be reached around 2140.
The underlying technology for bitcoin is the "blockchain," a type of distributed ledger technology. This technology uses complex mathematical algorithms in place of third-party financial institutions like banks or government agencies to verify transactions made with bitcoin or other digital tokens. Because bitcoin is not issued by any government or central authority, it is considered independent, and transactions using bitcoin are anonymous. It is theoretically not impossible to "crack" the blockchain; however, the technology was deliberately designed to be "computationally impractical to reverse," so it is very, very unlikely that one attempting to do so would succeed, at least in theory.
As of December 2017, the total value of all bitcoin tokens outstanding was estimated to be around $326.5 billion. To date (Feb. 2018), this is the highest total value bitcoin has ever reached.
Since the value of bitcoin surged in late 2013, it began to attract the attention of major media outlets as well as regulatory authorities. This led to the creation of new cryptocurrency regulation in the case of some countries (such as the U.S., Canada, and Russia), and outright bans in others (China, South Korea).
As of December 2017, about 40 percent of bitcoin was held by around 1,000 users. Holders of such large amounts of bitcoin are often called "whales."
With the volatility of bitcoin prices and values, hysteria and evangelism are not uncommon among the bitcoin community. The term "HODL" was popularized as a colloquial way of saying "Hold On for Dear Life", or simply "don't sell."
The bitcoin boom - bust - boom
In mid-December 2017, bitcoin's price hit a high of nearly $20,000 per BTC. Over the course of 2018, its price slowly but steadily declined. In September, Galaxy Digital's Michael Novogratz declared bitcoin had hit its new "bottom" at just over $6,400 per coin; the price of bitcoin remained relatively stable until mid-November when bitcoin saw an additional price decrease of almost 50 percent. By mid-December 2018, bitcoin's price had decreased by more than 80 percent compared to the highest price in December 2017. Some declared this to be the popping of the bitcoin "bubble."
By the summer of 2019, bitcoin began making a comeback. Bitcoin hit a new yearly high of $13,563.76 on June 27, 2019, before settling down around $11,500 on June 28. Many speculated that these huge gains were due to increased trading activity by institutional investors; Arthur Hayes, CEO of BitMEX, told Forbes earlier that week that daily trading volumes on his bitcoin margin trading platform surpassed $11 billion and were rapidly approaching $12 billion. Others speculated that the gains could be explained by Indian traders’ increased activity following the government’s recent proposed blanket ban on cryptocurrencies despite rising demand in the country. Whatever the reason, bitcoin’s price increased more than 300 percent since the start of the year.
Bitcoin's price crashed in March 2020, when a panic selloff caused by the coronavirus pandemic caused similar selloffs in just about every market - including so-called "safe haven" markets like gold. After the selloff, its price gradually began to climb throughout the rest of the year. In November, bitcoin's market price surpassed $19,834.93, beating its 2017 record.
Some attributed this to growing mainstream interest in bitcoin; fintech giants like PayPal had recently announced upcoming support for cryptocurrency trading. Billionaire investors like Ricardo Salinas Pliego, Mexico's third-richest man, had also recently posted on Twitter that he had ten percent of his liquid portfolio invested in bitcoin. Billionaire Ray Dalio, who previously expressed a negative attitude towards bitcoin, said that he "might be missing something about Bitcoin," and that he would "love to be corrected." Others argued that since the majority of bitcoin in circulation at the time was held by a relatively small number of people, known as "whales," and because the bitcoin market was still highly illiquid, any major price movement was likely due to whale activity in the cryptocurrency markets.
In December 2020, bitcoin's price exceeded $28K/BTC for the first time, resulting in its total market capitalization exceeding $500 billion.
Amid speculation that major commercial financial institutions like JPMorganChase and Morgan Stanley were about to buy bitcoin, the price of the digital asset rose above $50,000 on February 16, 2021. In April 2021, it reached as high as $61,742.
Using the NSA-developed SHA-256 cryptographic hash function as a proof-of-work function, Satoshi Nakamoto and their team created a system that could run on almost any platform to carry out anonymous, secure transactions that are extremely difficult to forge.
Of course, this process is not by any means a simple one. When a bitcoin miner attempts to add a "block" to the blockchain, they are receiving a transaction sent out into the blockchain network by someone with a "bitcoin wallet", or account containing their owned bitcoins. The computer or computers (nodes) of said miner then set out to calculate the solution to the SHA-256 problem using the wallet owner's "public key", a cryptographically-generated set of letters and numbers of varying lengths not tied to their personal identity in any way. This is used to solve a complex mathematical problem - called a hash function - in order to produce a digital address that will serve as the transaction's destination. This math problem can't be solved with simple logic, however; because of the anonymity of users and their hashes, the hash must be guessed. This creates a sort of contest between bitcoin miners to see who can guess a correct hash first. The bitcoin network increases the difficulty of this task in proportion to how many miners there are in the network, in order to keep the time between blocks created in the blockchain constant, around 10 minutes or so.
Blockchain is, theoretically, a widely-adaptable concept. Experimental startup companies have begun utilizing it for everything from supply chain management to ride sharing to birth and death certificate archiving. It was originally developed by Satoshi Nakamoto in order to create a peer-to-peer system of managing and verifying all transactions made with bitcoin. The blockchain ensures that all records of transactions made with bitcoin are securely archived. This ensures that, since new blocks of data are added by the bitcoin software client (which is also the sole proprietor of newly-mined bitcions), the total number of bitcoins in circulation and the number of bitcoins possessed by each user is maintained accurately, while also maintaining total anonymity of all users.
Transactions between bitcoin users are made with bitcoin wallets over bitcoin exchanges. Some popular exchanges include Coinbase (GDAX), Kraken, and Bitfinex. There are, however, several exchanges around the world, including several that operate on a national level.
On May 6, 2019 Bluewallet, a bitcoin wallet provider, launched wallet software allowing users to send bitcoin payments over the Lightning Network using Apple Watches. The software is available for download in the Apple iTunes Store. Nuno Coehlo, Head of product development for Bluewallet, noted that both the implementation of bitcoin payments in a smart watch as well as the lightning network are both highly expermimental. Coelho told CoinDesk, “It’s a very early stage industry so we’re trying to figure out how to build this stuff properly.”
Executing a bitcoin transaction involves paying fees of varying size. These are meant to incentivize miners to prioritize transactions offering nonzero fee rates first. The miner who solves the transaction and adds the resulting block to the blockchain receives the fee, like a waiter receiving a tip at a restaurant. Though bitcoin fees are meant to be optional gratuities, the act of assigning fees to a transaction has become commonplace; as a result, users who do not utilize fees can expect to wait much longer for their transactions to be verified. The time it takes for a transaction to become verified also depends on the volume of users making requests to alter the blockchain; in mid-December of 2017, the average wait time for transaction verification was around 78 minutes, but on Sunday the 17th, the average was closer to 1,188 minutes. At this time, the average fee needed to make a bitcoin transaction was approximately $28. By March 1st of 2018, that average had plummeted to $2.37.
Fees are often calculated using algorithmic software built into a cryptocurrency exchange, but they can also be entered manually. The rates for fees and the manner in which they are collected varies depending on the exchange; for example, the transaction fees of Kraken involve taking into account a rebate disbursed to its user's wallets, depending on when they are processed and what the rates relative to market volume are at the time the transaction is made.
One of the major functions of bitcoin is its ability to allow users to transact with one another with greater privacy than can be conferred (legally) by the traditional financial system.
At the Bitcoin 2019 conference in June 2019, Edward Snowden - a former NSA operative known for whistleblowing his former employer's mass surveillance efforts - spoke about how bitcoin allowed him to pay journalists in 2013 while on the run from the U.S. government. He said that "lack of privacy is an existential threat to bitcoin," and that privacy is "the only protection users have from political change." He also said that it is imperative for cryptocurrency exchanges not to give out client data, fearing that if one exchange did so, many others would follow.
Some of the more prominent bitcoin exchange entities are listed below:
In 2017, the Chicago Mercantile Exchange and the Cboe Futures Exchange (CFE) self-certified new contracts for bitcoin futures products, and the Cantor Exchange self-certified a new contract for bitcoin binary options.
LedgerX, a trading and clearing platform for digital assets, received approval for its platform from the CFTC in July of 2017 and began listing physically settled one- to six-month options contracts for bitcoin in October 2017. Other digital currency contracts such as Ethereum options are expected to follow.
The CFE launched trading in Cboe bitcoin futures on December 10, 2017 under the ticker symbol "XBT". The CME launched its own bitcoin futures contract a week later (Dec. 17) under the ticker "BTC." The Cboe settled its futures against a daily price auction from Gemini, while the CME uses its own bitcoin reference rate which tracks several cryptocurrency exchanges.
On October 3, 2018, ErisX announced its formation as the successor to Eris Exchange, a designated contract market that listed interest rate swap futures products. The company said it planned to trade and clear cryptocurrency futures contracts at some point. The exchange also said that it would offer spot trading. According to ErisX, its investors include DRW Venture Capital, Valor Equity Partners, TD Ameritrade, Virtu Financial, NEX Opportunities, Cboe Global Markets, CTC Group Investments, Digital Currency Group, Nico Trading, Pantera Capital, Third Stone Partners, CMT Digital, Susquehanna International Group, XR Trading, C2 Capital Management and ED&F Man Capital Markets Inc.
In March 2019, Cboe made a surprise decision to delist its bitcoin futures contract, with the final settlement of the contract on June 19, 2019. It had steadily lost market share to CME Group and open interest volume at CME was almost six times higher than Cboe's contract. CME posted record volumes in its bitcoin futures contract in 2019.
In February 2019, the CME Group announced that in the first quarter of 2019, it set a new record for total bitcoin futures contracts traded. The record high for total contracts traded in Q1 of 2019 was 18,338 contracts as of February 19th, the equivalent of 91,960 BTC or $360 million based on the price of bitcoin at the time. The previous record was set on November 20, 2018. On April 4, 2018, the CME Group Tweeted that the firm had experienced a "record trading day" on bitcoin futures; according to a chart accompanying the Tweet, 22,542 bitcoin futures had traded on April 4 alone, which is equivalent to 112,710 bitcoins.
ErisX announced on April 30, 2019, that it had closed another $20 million in funding from investors and that it was launching its spot market as well as related clearing services that day. Bitcoin was one of the initial cryptocurrencies that could be traded with its new services, as well as Bitcoin Cash, Litecoin, and Ethereum traded against the U.S. dollar and against each other. In an interview with CoinDesk, Chief Strategy Officer Matt Trudeau said that ErisX continues to build out its technology, raise funds, and apply for futures and futures clearing licenses.
The CME Group saw a record high number of bitcoin futures contracts traded, as well as the highest number of customer accounts trading bitcoin futures in its history in May 2019. The company released a statement saying, "the number of unique accounts continues to grow showing that the marketplace is increasingly using BTC futures to hedge bitcoin risk and/or access exposure." This trend would continue into the Summer of 2019; on June 17, the CME Group's open interest for bitcoin futures grew by a record 643 contracts in a day, reaching an all-time high of 5,311 contracts. Based on bitcoin's price at the time, this equated to over $250 million worth of contracts. Coinciding with this, the price of bitcoin reached $9,300, its highest point since May 2018. Around the same time, the Japanese Consumer Affairs Association (CAA) released a report saying that an increase in queries to Japanese exchanges related to bitcoin trading indicated increased interest in cryptocurrency trading.
Bitcoin is, by design, not backed by any government or financial institution. This means that it is not insured or well-regulated, so those who suffer losses as a result of investing in bitcoin, such as victims of fraud or theft, do not have the options for recourse that investors in the traditional financial system do. Originally, the United States Securities and Exchange Commission (SEC) released an Investor Alert document that described bitcoin as a "ponzi scheme" in 2013. As bitcoin and other cryptocurrencies have grown in popularity and steps toward greater regulation of the crypto space have been taken, the SEC's take on bitcoin has tentatively become more agreeable.
The IRS treats Bitcoin as property, for taxation purposes. Employees paid in bitcoin or other cryptocurrencies must be reported by an employer on a Form W-2, and are subject to federal income tax withholding and payroll taxes.
United States federal law does not provide for direct, comprehensive oversight of underlying Bitcoin or virtual currency spot markets. As a result, U.S. regulation of virtual currencies has evolved into a multifaceted, multi-regulatory approach. State banking regulators, the Internal Revenue Service (IRS), the United States Treasury's Financial Crimes Enforcement Network (FinCEN), and the Securities and Exchange Commission (SEC) monitor bitcoin and cryptocurrency trading to enforce state money transfer, tax, anti-money laundering, and fraud protection laws.
On March 25, 2014 the Internal Revenue Service announced that bitcoin should be viewed and taxed as property and not as currency. This meant that employers who pay wages in bitcoins would have to report those wages like any other payment made with property, and that bitcoin income will be subject to federal income withholding and payroll taxes. The agency's official statement declared, “it does not have legal tender status in any jurisdiction."
In May 2014 the U.S. Federal Election Commission voted to allow political committees to accept bitcoin donations.
In March of 2017 the SEC refused to grant an exemption that would have let the Winklevoss Bitcoin Trust ETF trade on the Bats BZX Exchange.
Bitcoin as a commodity
Bitcoin is classified by the Commodity Futures Trading Commission (CFTC) as a commodity, under the Commodity Exchange Act (CEA). The CFTC enforces all bitcoin derivatives contacts in the U.S., as well as all fraud and manipulation protection laws.
In September 2014 the CFTC permitted TeraExchange, a swap execution facility, to certify to the commission that its bitcoin swap complied with the requirements of the Commodity Exchange Act, a statement which implied that bitcoin is a commodity under the CFTC's authority. That December, Chairman Tim Massad stated his view during Congressional testimony that bitcoin was a commodity and acknowledged that the CFTC defined the term "commodity" broadly. In 2015 the CFTC settled a complaint against a company called Coinflip for providing, during 2014, a marketplace called Derivbit, which listed bitcoin options without being registered as a swap execution facility - the only permissible venue for commodity options trading. The CFTC settled its case against Bitfinex, wherein the CFTC accused Bitfinex of trading off-exchange Bitcoin futures and failing to register as a futures commission merchant, in June 2016. The view that bitcoin can be regulated as a commodity received support on March 6, 2018 when U.S. District Judge Jack Weinstein ordered that the CFTC could sue Patrick McDonnell and his company, CabbageTech, for fraud under the Commodity Exchange Act. CabbageTech solicited funds from investors for providing cryptocurrency advisory services, which the CFTC alleged were never forthcoming. 
Because much of the bitcoin and cryptocurrency trading that occurs happens via cash markets, the dark web, or other online methods which may not be totally secure or regulated, potential investors or traders of such should be highly vigilant of fraud. Buyers can verify whether a party offering bitcoin or other cryptocurrency options or futures services are registered with the CFTC using SmartCheck.gov, a consumer protection website owned and operated by the United States federal government.
As with regular brokers and investment professionals, consumers can use the CFTC's website Smartcheck.gov to look up investment professionals to see if they are registered and accredited by the CFTC.
Bitcoin was named as the currency of choice for the Russian intelligence officers indicted by the U.S. Government for spying on the Democratic National Committee - including hacking into their computers - during the 2016 presidential campaign. The indictment indicated that in addition to using bitcoin for payments, the intelligence officers mined new bitcoin. Along with the other complaints against them, the officers were charged with money laundering connected to their bitcoin use.
In October 2018 Nouriel Roubini, an economist and New York University professor famous for correctly predicting the popping of the U.S. housing bubble in 2007, called cryptocurrency and bitcoin "the mother or father of all scams and bubbles" while testifying at a congressional hearing on Capitol Hill. He said that everyone he knew that was actively involved in cryptocurrency trading was "financially illiterate," and "could not tell the difference between stocks and bonds."
Similar to "boiler room" fraud schemes, which aggressively pushed penny stocks on investors by misleading them about their potential future value, some individuals or organizations have used social media to mislead victims into investing their money in altcoins, or alternative cryptocurrencies. These "pump-and-dump" ICO scams use misinformation to trick large numbers of people into investing in a new digital asset with the promise of huge returns, then sell all of their shares once its price reaches a certain point, causing a significant price drop, leaving investors with essentially worthless digital tokens. Some use false news reports, testimony from fake "experts," and other unscrupulous means to accomplish their goals. The CFTC warns potential investors that they should be especially wary of very new cryptocurrencies, and that extensive research on a particular company or coin is imperative for potential investors. Fraudulent digital asset scams can be reported at Whistleblower.gov.
"IRS-approved" Digital Asset IRA's
Some frauds have advertised "IRS-approved" IRA funds and similar services involving digital assets. These typically rely on misinforming potential investors (for one thing, the IRS never endorses investments). Because self-directed IRA's can hold unregistered investments and are not taxed until withdrawn from an IRA account, they make for attractive, if false, potential investments to the unwary consumer.
Bitcoin was invented by a programmer or programmers using the name Satoshi Nakamoto. In 2008, Satoshi published a whitepaper entitled, "Bitcoin: A Peer-to-Peer Electronic Cash System" on the Cryptography Mailing List Metzdowd.com. In this paper, Satoshi proposed an alternative to traditional fiat currency in favor of "a purely peer-to-peer version of electronic cash [that] would allow online payments to be sent directly from one party to another without going through a financial institution." In 2009, Satoshi released the first bitcoin software client, as well as the first mined bitcoins, marking the launch of bitcoin.
The very first blockchain component, or "Genesis Block," was recorded on January 3, 2009. This coincided with the release of the original software client. The first recorded cryptocurrency transaction occurred nine days later, on January 12, 2009.
On May 22, 2010, Florida resident Laszlo Hanyecz traded 10,000 BTC for two pizzas from a Papa John's franchise. This is widely believed to be the first instance in which bitcoin was directly used to purchase something tangible. Since then, this occasion has been celebrated every May 22nd by bitcoin enthusiasts as "Bitcoin Pizza Day."
For the first several years after its creation, bitcoin held limited appeal. By 2011, multiple prominent Internet-based institutions began accepting donations through Bitcoin, including WikiLeaks, FreeNet, the Internet Archive, and the Free Software Fondation. By 2012, the Orlando-based bitcoin payment processing company BitPay announced that over 1,000 merchants had signed up for its service within the previous year. In 2013 the value of the virtual currency exploded, with prices moving from $13 to over $1200. By 2017, a number of extremely high-profile companies, including Microsoft, Expedia, Subway, and Newegg.com had begun accepting Bitcoin payments.
The CME Group, in collaboration with Crypto Facilities Ltd., a digital assets trading platform, launched CME CF Bitcoin Reference Rate (BRR) and CME CF Bitcoin Real Time Index (BRTI) on November 14, 2016. BRR provides a final settlement price in U.S. dollars at 4 PM London time on each trading day, and RTI gives users real-time access to bitcoin prices.
In March of 2017 Bitcoin's price plunged briefly and then recovered after the SEC refused to grant an exemption that would have let the Winklevoss Bitcoin Trust ETF trade on the Bats BZX Exchange.
In June 2017, the market cap for all cryptocurrencies surpassed $100 billion, due to a 300% increase that occurred in just over 2 months.
Since bitcoin launched in 2009, thousands of cryptocurrencies have been created, many of which have since failed. In fact, a report by Chris Skinner in 2018 revealed that only 8% of ICOs that launch survive, and that 50% that had launched in 2017 had already failed. At time of writing (February 28, 2018), there are currently 2943 in-market cryptocurrencies worldwide, including bitcoin, Ethereum, and Ripple.
In 2018, U.S. Federal investigators discovered that bitcoin was the currency of choice for the Russian hackers charged with influencing the 2016 U.S. Presidential election. The hackers allegedly used bitcoin to launder approximately $95,000 to pay companies such as the Romanian company dcleaks.com in their efforts. This was done in order to avoid direct relationships with financial institutions by utilizing the anonymity of bitcoin's transactions.
On Halloween 2018, the ten-year anniversary of bitcoin's whitepaper being published, bitcoin was trading at around $6,250 per coin.
On January 27, 2014, BitInstant founder Charlie Shrem was arrested at JFK International airport returning from a conference in Amsterdam. His company, which allowed users to digitally exchange bitcoins for fiat currency, had knowingly transferred money for criminals trading on the Silk Road website. Although Shrem had been aware of this, and sent an email to the user telling them, "you better stop," Shrem did not inform Federal authorities. This led to BitInstant closing its doors for good, and Shrem sentenced to two years in prison. Shrem became the first high-profile cryptocurrency luminary to be convicted on felony charges.
In 2014 Mt. Gox, one of the world's first-ever bitcoin exchanges, ceased operations indefinitely following a series of hacking attacks that caused its customers to lose millions of dollars worth of crypto. Mark Karpelès, the CEO of Mt. Gox, faced several lawsuits and criminal charges as a result. In 2016, a Russian hacker named Alexander Vinnik was arrested in Greece after numerous law enforcement agencies from the U.S., as well as independent investigators, traced some of the bitcoins stolen from Mt. Gox to a wallet owned by Vinnik. Vinnik was charged with helping criminals launder money through BTC-e, an exchange he allegedly ran.
Bitcoin Cash hard fork
Bitcoin made the most significant change in its 9-year history in July of 2017 when it split into two currencies after a splinter group launched a newer version of the currency with a different configuration. The two competing currencies are known as Bitcoin and Bitcoin Cash. The group behind Bitcoin Cash copied bitcoin’s software, added a couple of new features, and released it to the public. It will be an almost identical copy, and anybody who has a bitcoin balance can automatically hold the exact same amount of Bitcoin Cash. The main difference between the two is how fast they trade and how many trades can happen in a short amount of time.
Bitcoin "toxic" culture debate
In May 2019, cryptocurrency users on Twitter became engaged in a broad debate about the nature of the bitcoin community. Specifically, the debate questioned whether the culture within the bitcoin community was "toxic" - that it encourages those involved with it to think and behave in ways that are overly cynical and non-constructive. Certain Ethereum developers even said that they had chosen to leave the bitcoin community and begin programming for Ethereum due to the toxicity of bitcoin's community. Blockstream's Marketing Director Neil Woodfine said over Twitter that bitcoin "deals with money" - specifically, "separating money from the state." He said that it involves managing people's livelihoods, but that the "vast majority" bitcoin's community has seen many fraudsters and scammers, and has grown to be "necessarily one of extreme skepticism, cynicism, rigorous review, and forthright language," and that bitcoin "is better for it." He also said that those who disagree with this stance are "not good under pressure," "too sensitive," and "lack conviction." While many praised his argument, some like the director of MIT's Digital Currency Initiative Neha Narula accused Woodfine of gaslighting critics of bitcoin's culture, saying, "Always question, never settle, and know that there are lots of us who try to debate, criticize, learn, and improve without being jerks." Chaincode developer John Newbery made similar criticisms, saying that bitcoin's culture is still developing, is not set in stone, and can and should be improved.
John Lothian News Special Report, December 2013
On December 7, 2013, John Lothian News published a special report, "A Bitcoin for Your Thoughts" featuring:
