The Whitepaper Release
Satoshi Nakamoto posts "Bitcoin: A Peer-to-Peer Electronic Cash System" to the cryptography mailing list.
On October 31, 2008, an anonymous developer using the pseudonym Satoshi Nakamoto published a 9-page paper describing a decentralized digital currency system. The paper proposed using proof-of-work to achieve consensus without a trusted third party, solving the double-spending problem that had plagued previous digital cash attempts.
Block 0 & The First Tx
Genesis block mined. Nine days later, Satoshi sends 10 BTC to Hal Finney.
On January 3, 2009, Satoshi mined the genesis block (Block 0), embedding the headline "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" as a timestamp and political statement. On January 12, the first Bitcoin transaction occurred when Satoshi sent 10 BTC to cryptographer Hal Finney in Block 170.
Bitcoin Pizza Day
Laszlo Hanyecz pays 10,000 BTC for two pizzas. The first documented physical purchase.
On May 22, 2010, programmer Laszlo Hanyecz made the first known real-world Bitcoin transaction, paying 10,000 BTC for two Papa John's pizzas worth about $41. This established Bitcoin's first real-world exchange rate at roughly $0.0041 per coin. Those 10,000 BTC would later be worth over $1 billion.
The 184 Billion Bug
A value overflow bug allowed creation of billions of BTC. Fixed within hours via hard fork.
On August 15, 2010, a critical vulnerability was exploited in Block 74638, generating 184.467 billion BTC out of thin air — far exceeding the 21 million cap. Satoshi and developers quickly released a patch and the chain was rolled back. This remains the most serious bug in Bitcoin's history and demonstrated the community's ability to respond to critical threats.
First Exchange Rate Parity
Bitcoin reaches $1 for the first time — achieving parity with the US dollar.
In February 2011, Bitcoin achieved a symbolic milestone by reaching parity with the US dollar on the Mt. Gox exchange. This moment validated Bitcoin as a legitimate store of value for early adopters and attracted a wave of new interest from technologists and libertarians who saw its potential as an alternative monetary system.
Satoshi's Last Known Communication
Satoshi Nakamoto sends a final email stating "I've moved on to other things" and disappears.
In late April 2011, Satoshi Nakamoto sent what is believed to be the final communication, an email to developer Mike Hearn stating "I've moved on to other things. It's in good hands with Gavin and everyone." Satoshi had been gradually withdrawing from the project, handing off the alert key and source code repository access to Gavin Andresen. To this day, Satoshi's true identity remains unknown.
First Major Bubble & Crash
Bitcoin surges to $31 before crashing 94% to $2 — the first boom-bust cycle.
In June 2011, Bitcoin experienced its first major speculative bubble, surging from under $1 to $31.91 on the Mt. Gox exchange. This was driven by a Gawker article about Silk Road and growing media attention. The bubble popped spectacularly, with the price crashing 94% to around $2 by November 2011. This cycle established the pattern of dramatic boom-bust cycles that would repeat throughout Bitcoin's history.
The 1st Halving
Reward drops to 25 BTC. The "Halving Cycle" narrative begins.
On November 28, 2012, at block 210,000, the Bitcoin block reward was cut in half from 50 BTC to 25 BTC for the first time. This programmatic reduction in new supply — hardcoded into Bitcoin's protocol — marked the beginning of the "halving cycle" narrative. In the 12 months following, Bitcoin's price rose from $12 to over $1,000, establishing the pattern of post-halving bull runs.
Silk Road Takedown
FBI arrests Ross Ulbricht and seizes 144,000 BTC. Bitcoin survives the media backlash.
On October 2, 2013, the FBI arrested Ross Ulbricht (Dread Pirate Roberts) and shut down Silk Road, the darknet marketplace that had become Bitcoin's most notorious use case. The government seized approximately 144,000 BTC. Despite predictions that this would destroy Bitcoin, the price actually rose in the following weeks, proving Bitcoin's resilience was independent of any single use case.
BTC Hits $1,000 for First Time
Bitcoin breaks the four-figure barrier, driven by Chinese exchange volume and post-halving momentum.
In late November 2013, Bitcoin crossed $1,000 for the first time on the Mt. Gox exchange, fueled by massive trading volume from Chinese exchanges like BTC China. The price briefly touched $1,242, surpassing gold's per-ounce price. This rally was driven by the first halving's supply shock, growing mainstream media coverage, and a surge of interest from Chinese investors seeking alternative stores of value.
The Mt. Gox Bankruptcy
Largest exchange collapses. 850,000 BTC missing. Price crashes from $1,200 to $200.
In February 2014, Mt. Gox — once handling over 70% of all Bitcoin transactions — suspended trading, closed its website, and filed for bankruptcy. Approximately 850,000 BTC (worth ~$450M at the time) were reported missing due to years of undetected hacks. The collapse sent Bitcoin's price from over $1,200 to below $200 and shook confidence in the entire cryptocurrency ecosystem for years.
Newsweek "Finds" Satoshi
Newsweek claims Dorian Nakamoto is Bitcoin's creator. He denies it. The mystery continues.
On March 6, 2014, Newsweek published a cover story claiming to have found Bitcoin's creator — a 64-year-old Japanese-American man named Dorian Prentice Satoshi Nakamoto living in suburban Los Angeles. Dorian denied any involvement and was later supported by a message from the real Satoshi's P2P Foundation account stating "I am not Dorian Nakamoto." The incident highlighted the media frenzy and enduring mystery surrounding Bitcoin's creator.
The 2nd Halving
Block reward drops from 25 BTC to 12.5 BTC at block 420,000.
On July 9, 2016, Bitcoin's second halving occurred at block 420,000, reducing the mining reward from 25 BTC to 12.5 BTC. The price was relatively stable around $650 at the time. Over the following 18 months, Bitcoin embarked on its most dramatic bull run yet, eventually reaching $20,000 in December 2017 — confirming the halving cycle thesis for many investors.
Bitfinex Hack
119,756 BTC stolen. Exchange issues recovery tokens to socialize losses.
On August 2, 2016, the Bitfinex exchange was hacked and 119,756 BTC (worth ~$72 million at the time) were stolen. Rather than declaring bankruptcy like Mt. Gox, Bitfinex distributed losses across all users via "BFX tokens" that could later be redeemed or converted to equity. The exchange eventually repaid all users, setting a new precedent for hack recovery in the crypto industry.
SegWit & The BCH Fork
Segregated Witness activates. Disagreement leads to the Bitcoin Cash fork.
On August 1, 2017, Bitcoin Cash (BCH) forked from Bitcoin at block 478,558, advocating for larger blocks (8MB vs 1MB). On August 24, Segregated Witness (SegWit) activated on Bitcoin, increasing effective block capacity and enabling the Lightning Network. This "civil war" represented a fundamental disagreement about Bitcoin's scaling approach: small blocks + Layer 2 vs. big blocks on-chain.
Bitcoin Hits $20,000
Bitcoin reaches its first major all-time high as retail mania peaks during the ICO boom.
On December 17, 2017, Bitcoin reached a then-all-time high of $19,783 on some exchanges (briefly topping $20,000 on others). The rally was fueled by the ICO boom, massive retail speculation, and wall-to-wall mainstream media coverage. Bitcoin had risen from under $1,000 in January to nearly $20,000 in December — a 2,000% gain that captured global attention and brought millions of new investors into crypto.
CME & CBOE Bitcoin Futures
CME Group and CBOE launch Bitcoin futures — Wall Street's first regulated BTC derivatives.
In December 2017, CBOE launched Bitcoin futures on December 10, followed by CME Group on December 18. These were the first regulated Bitcoin derivatives products offered by major US exchanges. The launch legitimized Bitcoin as a financial asset class and gave institutional investors their first easy way to gain exposure to (or short) Bitcoin. The CBOE later discontinued its product, but CME futures became a cornerstone of institutional trading.
The Great Crash of 2018
Bitcoin begins a year-long decline from $20K to $3,200 — an 84% drawdown.
Starting in January 2018, Bitcoin entered the longest and deepest bear market in its history. From the $20,000 peak, the price fell relentlessly over 12 months, eventually bottoming at approximately $3,200 in December 2018. The crash wiped out over $700 billion in total crypto market cap, bankrupted many ICO projects, and led to widespread declarations that Bitcoin was "dead." Those who held through the crash were called "HODLers."
The Hash Wars (BCH vs BSV)
Bitcoin Cash splits into BCH and BSV in a contentious hash power battle.
In November 2018, the Bitcoin Cash community split in a bitter "hash war" between two competing factions. Craig Wright's Bitcoin SV (Satoshi's Vision) faction pushed for 128MB blocks, while Roger Ver's Bitcoin ABC faction opposed the changes. The resulting fork and hash power battle contributed to a broader market crash, with Bitcoin falling from $6,400 to $3,200 in just two weeks. BSV went its own way while BCH continued as the dominant fork.
Xi Jinping Endorses Blockchain
China's president calls for accelerated blockchain adoption, BTC briefly surges 40%.
On October 25, 2019, Chinese President Xi Jinping publicly endorsed blockchain technology in a speech to the Politburo, calling for China to "seize the opportunity" in blockchain development. Bitcoin's price surged nearly 40% in 24 hours, from $7,500 to over $10,000, marking one of the largest single-day gains in its history. However, Chinese state media quickly clarified that the endorsement was for blockchain technology — not cryptocurrency — and the price retraced.
COVID Black Thursday
Bitcoin drops 50% in one day as global markets panic over COVID-19 pandemic.
On March 12-13, 2020 — known as "Black Thursday" — Bitcoin crashed from $7,900 to $3,800 in less than 24 hours, a 50%+ drop. This was part of a global market meltdown as the COVID-19 pandemic triggered worldwide lockdowns and panic selling across all asset classes. The crash tested Bitcoin's "safe haven" narrative but also marked the beginning of an extraordinary recovery, as unprecedented money printing by central banks made Bitcoin's fixed supply increasingly attractive.
MicroStrategy's First Bitcoin Purchase
Michael Saylor's firm buys 21,454 BTC for $250M — pioneering corporate treasury strategy.
On August 11, 2020, MicroStrategy announced the purchase of 21,454 BTC for $250 million as a treasury reserve asset, marking the first major publicly traded company to adopt Bitcoin as its primary treasury reserve. CEO Michael Saylor called Bitcoin "digital gold" and cited inflation concerns. This move opened the floodgates for corporate Bitcoin adoption and made MicroStrategy a de facto Bitcoin proxy stock.
Elon Musk Adds #Bitcoin to Bio
Musk changes his Twitter bio to "#bitcoin" — BTC surges 20% in hours.
On January 29, 2021, Elon Musk — then the world's richest person — changed his Twitter bio to simply "#bitcoin". The move sent Bitcoin surging from ~$32,000 to over $38,000 within hours, a 20% jump that added over $100 billion to Bitcoin's market cap. It was one of the clearest demonstrations of a single individual's ability to move crypto markets with a single word. The bio change preceded Tesla's $1.5 billion Bitcoin purchase weeks later.
Tesla Buys $1.5B in Bitcoin
Elon Musk's Tesla adds Bitcoin to its balance sheet, sending BTC above $44,000.
On February 8, 2021, Tesla disclosed in an SEC filing that it had purchased $1.5 billion in Bitcoin and planned to accept BTC as payment for its vehicles. The announcement sent Bitcoin surging past $44,000 to a new all-time high. Tesla briefly accepted Bitcoin payments before suspending the option in May 2021, citing environmental concerns about Bitcoin mining's energy usage. The company still holds a significant portion of its original purchase.
Coinbase IPO ($86B Valuation)
Coinbase goes public via direct listing on NASDAQ at an $86 billion valuation.
On April 14, 2021, Coinbase Global (COIN) debuted on NASDAQ via direct listing at a reference price of $250 per share, opening at $381 and achieving a peak market cap of approximately $86 billion. It was the first major crypto exchange to go public in the US, representing a watershed moment for the industry's mainstream acceptance. The IPO gave traditional investors direct exposure to crypto market growth without holding digital assets directly.
Tesla Suspends Bitcoin Payments
Musk tweets Tesla will no longer accept BTC over energy concerns — BTC crashes 15%.
On May 12, 2021, Elon Musk announced via tweet that Tesla would suspend Bitcoin payments for vehicle purchases, citing concerns over the "rapidly increasing use of fossil fuels for Bitcoin mining." Bitcoin immediately dropped from ~$54,000 to ~$46,000 and continued falling to $30,000 over the following weeks. The reversal came just 49 days after Tesla began accepting BTC. Musk stated Tesla would not sell its holdings and would resume payments once mining transitions to "more sustainable energy."
El Salvador: Legal Tender
President Bukele makes BTC legal tender. Volcano mining begins.
On September 7, 2021, El Salvador became the first country in the world to adopt Bitcoin as legal tender under the Bitcoin Law championed by President Nayib Bukele. The government launched the Chivo wallet, gave citizens $30 in BTC, and began purchasing Bitcoin for its national treasury. El Salvador also announced plans to mine Bitcoin using geothermal energy from volcanoes, earning it the moniker "Bitcoin Country."
Bitcoin ATH: $69,000
Bitcoin reaches an all-time high of $69,044 amid institutional adoption and inflation fears.
On November 10, 2021, Bitcoin reached a new all-time high of $69,044 on major exchanges. The rally was driven by the launch of the ProShares Bitcoin Strategy ETF (the first US Bitcoin futures ETF), growing inflation concerns, and continued institutional adoption. The peak marked the top of the 2020-2021 bull cycle, after which Bitcoin entered a prolonged bear market fueled by rising interest rates and a series of crypto industry collapses.
Tesla Sells 75% of Bitcoin Holdings
Tesla dumps $936M in BTC at near-bottom prices — Musk cites "uncertainty about COVID lockdowns in China."
In its Q2 2022 earnings report, Tesla revealed it had sold approximately 75% of its Bitcoin holdings for $936 million. The company had originally purchased $1.5 billion worth of BTC in early 2021, meaning it sold most of its stack at a significant discount near cycle lows around $20,000-$29,000. Musk said the sale was to maximize Tesla's cash position amid uncertainty about COVID lockdowns in China. Tesla retained ~11,509 BTC. The timing was widely criticized as selling near the bottom of the bear market.
Terra/LUNA Collapse
The $40B Terra ecosystem implodes, triggering a cascade of crypto failures.
In May 2022, the Terra/LUNA ecosystem — which included the UST algorithmic stablecoin and the LUNA governance token — collapsed in spectacular fashion. UST lost its dollar peg, and LUNA went from $80 to fractions of a cent in days, destroying approximately $40 billion in value. The contagion spread to Three Arrows Capital, Celsius Network, Voyager Digital, and others, triggering a chain reaction of bankruptcies that defined the 2022 crypto winter.
FTX / Alameda Collapse
SBF's empire falls after $8B hole discovered. Massive industry contagion follows.
In November 2022, FTX — the world's third-largest crypto exchange — collapsed in a matter of days after CoinDesk revealed that Alameda Research (FTX's sister trading firm) held billions in illiquid FTT tokens. A run on the exchange exposed an $8 billion shortfall. Founder Sam Bankman-Fried was arrested and later convicted of fraud. Bitcoin fell to $15,500, its lowest level since late 2020, marking the nadir of the crypto winter.
The 4th Halving
Block reward drops from 6.25 BTC to 3.125 BTC at block 840,000.
On April 19, 2024, Bitcoin's fourth halving occurred at block 840,000, reducing the mining reward from 6.25 BTC to 3.125 BTC. This was a unique halving — the first to occur with spot Bitcoin ETFs already trading, providing institutional demand to complement the supply reduction. The daily issuance of new Bitcoin dropped to approximately 450 BTC per day, continuing Bitcoin's march toward its 21 million supply cap.
The Spot ETF Approval
SEC approves 11 Spot ETFs including BlackRock. Institutional flow goes massive.
On January 10, 2024, the SEC approved 11 spot Bitcoin ETFs simultaneously, including products from BlackRock (IBIT), Fidelity (FBTC), and other major asset managers. This was the culmination of a decade-long effort and opened the floodgates for institutional capital. Within months, these ETFs attracted over $50 billion in assets under management, with BlackRock's IBIT becoming the fastest-growing ETF in history.
Bitcoin Surpasses Silver Market Cap
Bitcoin's market capitalization exceeds that of silver, becoming the 8th largest asset globally.
In March 2024, Bitcoin's market capitalization surpassed silver's estimated $1.4 trillion valuation, making Bitcoin the world's 8th largest asset by market cap. This milestone reinforced the "digital gold" narrative and demonstrated Bitcoin's growing acceptance as a legitimate store of value. The surge was driven by massive ETF inflows and pre-halving anticipation, with BTC briefly touching $73,000.
Pro-Bitcoin President Elected
A pro-crypto candidate wins the US presidential election, pledging to make the US a "Bitcoin superpower."
In November 2024, the US presidential election was won by a candidate who campaigned on pro-Bitcoin policies, including promises to fire SEC Chair Gary Gensler, create a national Bitcoin strategic reserve, and end the regulatory crackdown on crypto. The election result triggered a massive rally, with Bitcoin surging past $75,000 and eventually breaching $100,000. The shift in political sentiment was seen as a turning point for crypto regulation in the United States.
The $100,000 Breach
Fueled by the 4th halving and political shifts, BTC crosses 6 figures.
In January 2025, Bitcoin finally crossed the historic $100,000 mark — a psychological milestone that was once considered unthinkable. The convergence of the 4th halving's supply reduction, record ETF inflows exceeding $100 billion AUM, a pro-crypto US administration, and growing sovereign adoption created the perfect storm. The six-figure milestone was celebrated worldwide and marked Bitcoin's transformation from a niche experiment into a global macro asset.
Bitcoin Strategic Reserve Executive Order
Executive order signed to establish a US Bitcoin Strategic Reserve using seized BTC assets.
In December 2025, the US President signed an executive order establishing a national Bitcoin Strategic Reserve, directing the Treasury to hold and manage seized Bitcoin assets rather than auctioning them. The order also tasked a working group with evaluating additional Bitcoin acquisitions. This marked the first time a major Western government formally designated Bitcoin as a strategic reserve asset, following in the footsteps of El Salvador but at a much larger scale.
Bithumb "Ghost Bitcoin"
Data error creates 620,000 fake BTC on dashboards for 20 mins, causing flash crash.
In February 2026, the South Korean exchange Bithumb experienced a critical data error that displayed 620,000 non-existent "ghost" Bitcoin on its platform for approximately 20 minutes. The glitch triggered automated trading bots and panic selling, causing a brief flash crash before the error was identified and corrected. While no actual Bitcoin was created, the incident highlighted the fragility of exchange infrastructure and the outsized impact of data errors in high-frequency trading environments.
