Bitfinex, the largest Bitcoin exchange by volume, announced that 119,756 bitcoins of customer funds had been stolen via a security breach, a value roughly equivalent to $72 million USD. Bitfinex was holding the customer funds in multi-signature addresses in conjunction with its security partner BitGo. It is presumed that the attacker obtained access to the private keys for nearly all Bitfinex customer accounts, as well as access to the BitGo API for the Bitfinex account.
It remains unclear if the customer funds were insured by BitGo and if customers will be fully reimbursed.
The price of Bitcoin plunged nearly 20% to $480 USD that day before beginning a gradual recovery.
Others in the Bitcoin community suggested that prior knowledge of the upcoming hack was used by unknown entities for insider trading as the price had begun to drop significantly before Bitfinex's announcement.

Bitcoin value: $652.14 Bitcoin value 10 days later: $674.03
The block reward was decreased for the second time in Bitcoin's history, resulting in a new reward of 12.5 bitcoins per mined block. The automatic 50% drop continued Bitcoin's original design to gradually decrease the number of newly created bitcoins until the block reward ends completely, which is estimated to occur in the year 2140.
The block reward halving occurs every 210,000 blocks and the next "Halving Day" is expected to occur in July 2020.

Following a five month absence from the public eye, Craig Wright publicly announced he was Satoshi Nakamoto by means of a blog post. The blog post featured a disjointed demonstration of a private keysigning, which seemed to be an attempt to verify Wright was in possession of Nakamoto's private Bitcoin keys. This verification was later debunked by the Bitcoin community.
Wright's claim was backed up by Bitcoin developer Gavin Andresen in his own blog post earlier the same day. Andresen stated that he met with Wright in-person in London, and privately witnessed Wright sign an arbitrary message using one of Nakamoto's private Bitcoin keys.
Andresen later stated that he may have been tricked by Wright.

Mike Hearn Quits Bitcoin (a.k.a The Hearnia) - January 14, 2016
Bitcoin value: $431.76 Bitcoin value 10 days later: $397.92
In a public blog post, Mike Hearn declared that Bitcoin had failed and that he will "no longer be taking part in Bitcoin development". Hearn was an ex-Google developer who had been heavily involved in the Bitcoin community and related projects since the early days of the cryptocurrency. His most popular project was bitcoinj, a Java implementation of the Bitcoin protocol.
Hearn's post blamed Bitcoin's alleged failure on a number of reasons: censorship in the Bitcoin community, the centralization of mining to a handful of Chinese miners, and the unwillingness of Bitcoin Core developers to increase the limit on Bitcoin's block size. Within 24 hours of the post being published, Bitcoin's price dropped over $50 USD.
Others in the Bitcoin community accused Hearn of purposely attacking Bitcoin in order to promote his new employer, R3 CEV, a startup focused on using blockchain technology to improve the operations of the global banking industry.

Bitcoin value: $397.52 Bitcoin value 10 days later: $461.05
Security researcher and writer, Gwern Branwen, published an article in WIRED magazine claiming that an Australian man named Dr. Craig S. Wright was either Satoshi Nakamoto or a "brilliant hoaxer". Gwern cited a number of Wright's deleted blog posts, leaked emails, and transcripts that seemed to suggest Wright is Bitcoin's creator. In one leaked transcript Wright himself claims "I did my best to try and hide the fact that I’ve been running bitcoin since 2009". Another document detailed that Wright had access to a Bitcoin trust worth 1.1 million bitcoins.
However, none of the leaked documents Gwern claimed to possess were published.
Wright did not provide WIRED with any confirmation that he was indeed Satoshi Nakamoto. Within hours of the article being published, Wright's existing online presence was mostly removed from the web.

Gemini Exchange Launched - October 8, 2015
Bitcoin value: $245.48 Bitcoin value 10 days later: $268.01

Bitcoin value: $267.24 Bitcoin value 10 days later: $214.3
Bitcoin Core developers Mike Hearn and Gavin Andresen released a separate version of the Bitcoin client software, called Bitcoin XT. The release illustrates an ongoing controversy in the Bitcoin development community: what limit should be placed on the size of Bitcoin's blocks? Bitcoin XT implements BIP 101, which proposes "replacing the fixed one megabyte maximum block size with a maximum size that grows over time at a predictable rate".
The release of Bitcoin XT culminated fears that the Bitcoin community may not be able to reach a consensus on the issue, and the blockchain may hard fork, resulting in two separate versions of Bitcoin's global ledger.

Bitcoin value: $226.9 Bitcoin value 10 days later: $232.05
Superintendent of New York State Department of Financial Services, Benjamin Lawsky, released a set of customized rules meant to regulate Bitcoin and digital currency businesses that serve customers located in New York state. These regulations are the first ever directly targeted at digital currency businesses.

A BitLicense application costs $5,000 and the regulations include a number business requirements, such as fingerprinting employees for the FBI, obtaining written approval of all new business activities, and retained "earnings and profits of the company can only be invested in US dollars".
In response, New York based customers were banned and expunged by a number of Bitcoin companies, including Bitfinex, Kraken, Bitquick.co, and ShapeShift.
Ross Ulbricht Sentenced to Life in Prison - May 19, 2015
Bitcoin value: $234.31 Bitcoin value 10 days later: $238.22
After a month-long jury trial that ended in Ulbricht's conviction, Judge Katherine Forrest sentenced Ulbricht to life in prison without parole. Ulbricht had been found guilty on 7 charges of money laundering, computer hacking, and conspiracy to traffic narcotics in February due to his role as the operator of the Silk Road marketplace (a.k.a "Dread Pirate Roberts"). In a letter to Judge Katherine Forrest prior to his sentencing, Ulbricht admitted to running the Silk Road and made a plea for leniency. The judge's sentencing statement hinted that the harshness of the sentence was to make an example of Ulbricht: members of the public considering following in his footsteps should know "that if you break the law this way, there will be very serious consequences."
Ross Ulbricht would later appeal the ruling on June 5, 2015.
Coinbase Launches US Licensed Exchange - January 26, 2015
Bitcoin value: $281.26 Bitcoin value 10 days later: $222.85
The VC backed startup Coinbase Inc., a popular Bitcoin outlet and payment processor, announced the release of its own Bitcoin trading platform. The company founders stated they had worked for months to obtain various licenses from state financial regulators, allowing them to legally accept customers from 25 different US states.
The new platform will operate like a traditional exchange: customers can deposit funds, place asks and bids on an order book, and will be charged a small percentage fee on executed trades. The exchange platform is to remain separate from their Bitcoin outlet operation, which in contrast, allows customers to buy and sell Bitcoins directly from Coinbase.
Bitstamp Hacked - January 4, 2015
Bitcoin value: $275.07 Bitcoin value 10 days later: $198.59
Unknown hackers were able to steal 18,866 bitcoins from Bitstamp's operational hot wallet, worth roughly $5.2 million dollars. The attackers used social engineering against Bitstamp system administrator Luka Kodric to gain access to 2 of Bitstamp's servers and subsequently the hot wallet's private keys. The wallet was completely drained of all bitcoins shortly thereafter.
Upon discovery of the breach, Bitstamp immediately shutdown the exchange's operations for 8 days as it audited its systems and rebuilt its trading platform.
The theft represented "a small fraction of Bitstamp's total bitcoin reserves" as the majority of the company's Bitcoin funds remained untouched in offline "cold" storage. No customer account balances were affected. However, according to a leaked internal Bitstamp report on the incident, the damage to the company's reputation and customer confidence far exceeded its monetary Bitcoin loss.

The goal of the new regulations, according to Lawsky, are to help "protect consumers and root out illegal activity – without stifling beneficial innovation". The regulations would require entities that deal in Bitcoin to run background checks/fingerprints for all employees, get written approval for new business activities by the state, and to immediately convert any Bitcoin profit to US dollars. Affected entities would be exchanges, mining pools, bulk Bitcoin sellers, and altcoin software creators based in New York state, or that have customers in New York state. News of these regulations are generally rebuked by the cryptocurrency community.

Mining Pool GHash.io Reaches 51% - June 13, 2014
Bitcoin value: $598 Bitcoin value 10 days later: $592.28
Due to GHash.io's popularity and partnership with CEX.io to sell mining shares of their own mining hardware, the mining pool giant gains a sole majority of the Bitcoin network hashing power, and the ability to launch a successful 51% attack on the Bitcoin network. With a majority of the Bitcoin network hashing power, GHash.io could temporarily reverse transactions that they send (double spending) and prevent other transactions from being confirmed.
GHash.io responds by stating they "have and never will participate in any 51% attack". The pool also issues a press statement declaring that it will attempt to limit its hashing power to 39.99% by "actively asking miners to take their hardware away from GHash.IO and mine on other pools", as well as form a committee to assist Bitcoin core developers in solving the 51% attack problem.
Chinese Exchanges' Bank Accounts Closed - April 10, 2014
Bitcoin value: $408.25 Bitcoin value 10 days later: $501.7
The People's Bank of China's frequently updated restrictions against Bitcoin finally pressure some Chinese banks to issue a deadline against several bitcoin exchanges, requiring them to close their accounts by April 15. Although some are spared the warnings, the uncertain regulatory environment holds some prominent loopholes that virtually all Chinese exchanges quickly adopt. Using offshore banks, novel cryptographic voucher systems and other solutions, these trading platforms continue to operate, but at greatly reduced volumes from their hayday in 2013.
IRS Declares Bitcoin To Be Taxed As Property - March 26, 2014
Bitcoin value: $581.52 Bitcoin value 10 days later: $453.05
The IRS policy document declares Bitcoin to be property, not currency, subject to capital gains tax – with that tax calculated against every change in buying power for a given amount of bitcoin, from the time it's acquired to the time it's spent. The decision is widely derided as unwieldy and overly complex, requiring users of the currency to record Bitcoin's market price with every transaction, subject to an array of largely unfamiliar calculations. Others, however, remark that the net tax paid may often be less than if Bitcoin were treated as currency proper - but to a market that emerged in tax-free innocence, it is a difficult blow to soften.
Newsweek Claims Dorian Nakamoto is Bitcoin's Creator - March 6, 2014
Bitcoin value: $662.57 Bitcoin value 10 days later: $631.25
In an article titled "The Face Behind Bitcoin", journalist Leah McGrath Goodman writes that an unemployed engineer in Temple City, California is in fact Bitcoin's creator. Based on speculations and interviews with Dorian's family, Goodman's article ultimately draws an enourmous amount of worldwide attention to Dorian Nakamoto, who denies any involvement in Bitcoin and asks for privacy from the media.
The Bitcoin community would later go on to raise about $23,000 for Dorian Nakamoto.
Mt. Gox Closes - February 24, 2014
Bitcoin value: $547.09 Bitcoin value 10 days later: $662.57
After putting an abrupt halt to withdrawals on February 6, claiming that a hacker had exploited their own poorly-implemented software through the use of transaction malleability attacks, disgraced bitcoin exchange Mt. Gox's website and trading engine go blank without official comment. Other exchanges and Bitcoin businesses issue a joint statement condemning the mismanagement, deception, and eventual collapse wrought by the executives of the Japan-based exchange, after an alleged leaked internal document showed that over 744,000 BTC were lost by the company.
Major Exchanges Hit With DDoS Attacks - February 7, 2014
Bitcoin value: $717.83 Bitcoin value 10 days later: $626.5
Mt. Gox, Bitstamp, and BTC-e all experienced a stoppage of trading due to massive DDoS attacks that were apparently aimed at exploiting transaction maleability in the exchanges' software. Mt. Gox halted withdrawals first, on February 6, evidently contributing to a sharp drop in BTC price; the DDoS attack was detected on February 11, 2014.
Due to a host of problems at Mt. Gox, it may not be clear that the DDoS attack was primarily responsible for the problems they experienced on February 6th. 
Chinese Government Bans Financial Institutions From Using Bitcoin - December 5, 2013
Bitcoin value: $1022.37 Bitcoin value 10 days later: $839.93
Putting its first restraints on Bitcoin's surging popularity, the People's Bank of China declares Satoshi Nakamoto's novel invention not to be a currency. The policy change prohibits any financial institution to trade, insure, or otherwise offer services related to Bitcoin. Over the following weeks, further restrictions slowly strangle the Chinese cryptocurrency markets, as exchanges repeatedly try to find innovative, lasting ways to stay in operation, and prices around the globe sink dramatically.
Exchange Rate Peaks at $1,242 on Mt. Gox - November 29, 2013
Bitcoin value: $1132.26 Bitcoin value 10 days later: $921.97
Rapidly growing Bitcoin investment from China steadily drives prices higher and higher, reaching a peak on November 29th. Subject to strict controls concerning the movement of money across the country's borders, Chinese citizens embrace the freedom provided by Bitcoin with open arms, seeking an alternative to the state's inflating official currency, the Renminbi. The origin of mainstream Chinese interest in Bitcoin is largely credited to Jet Li's One Foundation, which publicized a Bitcoin address for donations in the wake of the April 20th, 2013 Lushan earthquake and received over 230 BTC in just two days, covered widely in the national media.
People’s Bank of China OK's Bitcoin - November 20, 2013
Bitcoin value: $641.23 Bitcoin value 10 days later: $1075.16
Speaking in Chinese at an economic forum, Mr. Yi says that “people are free to participate in the Bitcoin market,” and that he would “personally adopt a long-term perspective on the currency.” News of his statements energize the already active Chinese bitcoin markets, with the largest, BTC China, seeing trade volumes more than twice those of the world's second-largest exchange, Mt. Gox.

Bitcoin value: $685.75 Bitcoin value 10 days later: $1072.83
Announced under the title "Beyond Silk Road: Potential Risks, Threats, and Promises of Virtual Currencies," hope for the U.S. Government panel's discussion is dim among the Bitcoin community leading up to the hearing. As the proceedings commence, however, many of the panelists and Senators agree that Bitcoin holds great promise. The general consensus is summed up by Jennifer Shasky Calvery, Director of the U.S. Government's Financial Crimes Enforcement Network (FinCEN), who testified, “We want to operate in a way that does not hinder innovation.”

Bitcoin value: $133.03 Bitcoin value 10 days later: $135.12
Following a trail of clues left carelessly across the internet, the U.S. Federal Bureau of Investigation (in conjunction with other agencies) manages to identify the alleged operator of the dark web marketplace, which saw most of its sales in illicit drugs. Ross Ulbricht, claimed by the FBI to be the site's founder, Dread Pirate Roberts, is arrested in a San Francisco Public Library and charged with narcotics trafficking, computer hacking, money laundering and engaging in a “continuing criminal enterprise.” About 30,000 BTC of the Silk Road's alleged bitcoin holdings are seized at the time, and an additional 144,000 BTC from DPR's private holdings are swept up three weeks later.
Tradehill Shuts Down (Again) - August 30, 2013
Bitcoin value: $131.48 Bitcoin value 10 days later: $126.94
The business-to-business bitcoin exchange had been reliant on the relatively new Internet Archive Federal Credit Union to hold its clients' deposits in regulation-compliant, insured accounts. When the IAFCU determines that it can not reasonably handle the myriad regulatory issues surrounding Bitcoin, Tradehill is forced to halt operations and return customers' funds.
DHS Seizure Warrant Against Mt. Gox - May 14, 2013
Bitcoin value: $114.33 Bitcoin value 10 days later: $128.8
When Mt. Gox opened an American bank account with Wells Fargo, President and CEO Mark Karpelès answered “no” to the questions, “Do you deal in or exchange currency for your customer?” and “Does your business accept funds from customers and send the funds based on customers’ instructions (Money Transmitter)?” The U.S. Government thinks otherwise. With the warrant signed, Homeland Security Investigations seizes $2,915,507.40 from an account owned by a Mt. Gox subsidiary that was used to process payments to and from U.S. customers, and the future of Bitcoin's legal status becomes ever more uncertain.
Increased Trading Volume Breaks Mt. Gox - April 10, 2013
Bitcoin value: $181.66 Bitcoin value 10 days later: $122.9
Originally thought to be a Distributed Denial-of-Service (DDoS) attack on the largest bitcoin exchange, the great influx of traders on the heels of Cyprus's bailout announcement overwhelms Mt. Gox's servers, causing trades to stutter and fail. Speculative concerns about the exchange's hiccups feed a powerful panic-sell that saturates the market and drives prices down to pre-rally levels, before rising again a few days later.
Cyprus Bail-In - March 25, 2013
Bitcoin value: $74.02 Bitcoin value 10 days later: $131.07
Orchestrated by Cyprus President Nicos Anastasiades, the Eurogroup, the European Commission, the European Central Bank and the International Monetary Fund, the €10 billion bailout is hoped to fortify the flagging Cypriot economy. Among its conditions, however, is a sizable levy collected from most bank accounts with holdings over the €100,000 cutoff - a serious concern not just for wealthy Cypriots but many internationals, as the nation's favorable policies had made it a popular global tax haven, particularly in Russia. Seeking solutions to preserve their holdings before the bailout's conditions take effect, many of these account holders begin buying bitcoin en masse, driving a price rally through early April that brought the value of one bitcoin from about $80 to over $260.
Bitcoin 0.8 Causes Brief Hard Fork - March 11, 2013
Bitcoin value: $47.41 Bitcoin value 10 days later: $68.89
Shaking confidence in Bitcoin and the validity of some transactions, the price briefly plummets and the Mt. Gox exchange temporarily suspends bitcoin deposits. Thanks to a swift and coordinated response by Bitcoin developers, miners, and community members, the fork is resolved within hours after the operators of two large mining pools, Michael Marsee (of BTC Guild) and Marek Palatinus (of slush's pool), honorably forgo some of their accumulated mining rewards in order to downgrade to the previous, compatible version. An updated version, 0.8.1, is released shortly after, containing safeguards to prevent the original problem.
Halving Day - November 28, 2012
Bitcoin value: $12.25 Bitcoin value 10 days later: $13.43
In line with the original design for Bitcoin's maturation, the number of coins created to reward miners undergoes its first reduction, beginning the long and gradual process of tapering the amount of new currency entering the economy. These “Halving Days” are scheduled to occur every four years, stepping down the number of new bitcoins generated until the reward reaches 0 in the year 2140, to yield a fixed money supply of 20,999,999.9769 BTC. This pre-programmed limit to inflation is a major driver of the currency's economic controversy, value appreciation and speculation.
Wordpress Accepts Bitcoin - November 15, 2012
Bitcoin value: $11.04 Bitcoin value 10 days later: $12.46
In a smart and savvy release, Wordpress explains the decision: “PayPal alone blocks access from over 60 countries, and many credit card companies have similar restrictions... we don’t think an individual blogger from Haiti, Ethiopia, or Kenya should have diminished access to the blogosphere because of payment issues they can’t control. Our goal is to enable people, not block them.” As one of the 25 most popular domains on the web, Wordpress's move paves the way for later retail ventures in Bitcoin.

On July 23, 2013, the U.S. Securities and Exchange Commission files charges against Shavers for defrauding investors in a Ponzi scheme.

Mt. Gox Hacked - June 19, 2011
Bitcoin value: $17.77 Bitcoin value 10 days later: $16.88
By gaining access to the credentials of an official auditor working for the Mt. Gox bitcoin exchange, a hacker downloads a slightly out-of-date copy of the website's user database, including email addresses and insecurely hashed passwords. Using their newfound administrator-level access to the site, they place countless offers to sell bitcoins that don't exist, falsely deflating prices until the going rate reaches just $0.01 per coin. Mt. Gox reverses the fraudulent transactions and halts trading for seven days to re-secure their systems, and two other large exchanges issue temporary halts while their own security is reviewed. Soon after, a copy of the database is leaked and is used to launch attacks against accounts held by users of the MyBitcoin online wallet service who share the same password on both sites, resulting in thefts of over 4,019 BTC from roughly 600 wallets.

The oddity is quickly spotted by Bitcoin developers and community members, and a fixed version of the Bitcoin software is released within hours.
