Bitcoin History: Interactive Timeline of Major Events

October 31, 2008. An anonymous person or group using the name Satoshi Nakamoto published "Bitcoin: A Peer-to-Peer Electronic Cash System" to a cryptography mailing list. The nine-page paper described a decentralized monetary system secured by proof-of-work, with no trusted third party required to process payments.

The timing was notable: Lehman Brothers had collapsed six weeks earlier. The whitepaper's genesis block would later include the headline "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" — widely interpreted as a commentary on the fiat monetary system Bitcoin was designed to replace.

January 3, 2009. Satoshi Nakamoto mined the genesis block (block 0), creating the first 50 bitcoin and launching the Bitcoin network. The network had no monetary value at this stage — only Satoshi and a small number of cryptography researchers were running nodes.

The genesis block's coinbase transaction contains the famous Times headline, permanently etched into Bitcoin's ledger. This block is special: its 50 BTC reward is unspendable by protocol quirk.

May 22, 2010. Laszlo Hanyecz, a programmer in Florida, paid 10,000 BTC for two Papa John's pizzas — the first documented real-world Bitcoin transaction. At the time, Bitcoin had no established market price; the 10,000 BTC was worth approximately $41 based on forum exchange rates.

At Bitcoin's 2021 ATH of ~$69,000, those 10,000 BTC would have been worth ~$690 million. May 22 is now celebrated annually as "Bitcoin Pizza Day" in the community.

This established that Bitcoin had real-world purchasing power — a critical milestone for any monetary asset.

February 2011: Bitcoin reached $1 USD for the first time, achieving parity with the US dollar. By June 2011, it had reached ~$32 on the Mt.Gox exchange, driven by mainstream media attention including a Gawker article on Silk Road.

The crash: Within weeks, a hack of the Mt.Gox exchange (750,000 BTC stolen) and a broader market panic sent Bitcoin from $32 to $2 — a 94% drawdown. Many early adopters sold. Others accumulated. By 2012, Bitcoin had recovered to $13.

This established the pattern that would repeat across multiple cycles: extreme volatility, crisis, recovery, new ATH.

November 28, 2012. The first Bitcoin halving occurred at block 210,000. The block reward dropped from 50 BTC to 25 BTC, reducing the daily issuance of new Bitcoin by half. This was the first time the supply schedule encoded in Satoshi's original design had been executed in practice.

Price at first halving: approximately $12. Within 12 months, Bitcoin had surpassed $1,000 for the first time. Whether correlated or coincidental, this began the pattern of post-halving bull markets observed across subsequent cycles.

November 2013. Bitcoin crossed $1,000 on Mt.Gox — a milestone that brought mainstream financial media attention. The price had been driven by growing exchange volume, Silk Road notoriety, and early institutional curiosity. The US Senate held its first hearing on Bitcoin in November 2013, treating it as a legitimate payment system.

The move from $100 to $1,000 happened in a matter of weeks. From peak (~$1,100) Bitcoin would fall to ~$150 over the following two years — an 86% drawdown.

February 2014. Mt.Gox, which handled approximately 70% of all Bitcoin trades globally, suspended withdrawals and later filed for bankruptcy. 850,000 BTC (approximately $450 million at the time) had been stolen — most apparently through a slow drain spanning years, exploiting transaction malleability vulnerabilities.

This was the largest Bitcoin theft in history and the first major exchange failure. Bitcoin's price fell from ~$800 to ~$150 over the following year. It also demonstrated why self-custody is critical: exchange-held Bitcoin is not your Bitcoin.

July 9, 2016. The second halving cut the block reward from 25 BTC to 12.5 BTC. Bitcoin's price at the time was approximately $650. Within 18 months, it would reach $20,000 — a 30x move. The halving itself caused minimal immediate price movement, consistent with the view that markets partially price in known supply schedule changes in advance.

December 2017. Bitcoin reached approximately $20,000 on major exchanges, driven by retail investor mania, ICO speculation, and growing mainstream media coverage. CBOE and CME launched Bitcoin futures products in December 2017 — the first regulated Bitcoin derivatives in the US.

The broader market was flooded with altcoin initial coin offerings (ICOs), many of which were fraudulent. The speculative excess included dramatic stories of individuals mortgaging homes to buy Bitcoin at the peak.

From peak to trough: Bitcoin fell from ~$20,000 to ~$3,100 by December 2018 — an 84% drawdown. The bear market lasted approximately two years.

2018–2019. Bitcoin fell from ~$20,000 to ~$3,100 — an 84% peak-to-trough decline. The media declared Bitcoin dead. Many altcoins fell 95–99% and never recovered. This period is known as "Crypto Winter."

During this period: institutional custody solutions were built (Fidelity Digital Assets launched in 2018), regulatory frameworks were developed, and long-term holders accumulated. The bear market cleared speculative excess and built the foundation for the next cycle.

August 2020. MicroStrategy, a publicly traded business intelligence company led by Michael Saylor, announced it had purchased 21,454 BTC (~$250 million) as a primary treasury reserve asset. This was the first major public company to adopt Bitcoin as a treasury strategy — and the first to publicly frame it as a hedge against US dollar inflation.

Following MicroStrategy's announcement, other public companies, hedge funds, and eventually sovereign wealth vehicles began allocating to Bitcoin. PayPal announced Bitcoin buying and holding for US customers in October 2020. Square (now Block) purchased 4,709 BTC.

The third halving had occurred in May 2020 (reward → 6.25 BTC). By December 2020, Bitcoin had surpassed its 2017 ATH.

September 7, 2021. El Salvador became the first country to adopt Bitcoin as legal tender under President Nayib Bukele. Citizens received $30 in Bitcoin via the government's Chivo wallet. Merchants were required to accept Bitcoin for all transactions.

The International Monetary Fund (IMF) expressed concern and urged El Salvador to reverse the policy. The World Bank declined to assist with implementation. Despite this, El Salvador continued accumulating Bitcoin into the national treasury.

As of 2026, El Salvador has maintained and expanded its Bitcoin policy, with the IMF eventually softening its position as part of a $1.4 billion loan agreement. The El Salvador experiment remains the most significant nation-state adoption event in Bitcoin's history.

November 10, 2021. Bitcoin reached its current all-time high of approximately $69,000 on major exchanges, driven by ETF speculation (a ProShares Bitcoin futures ETF had launched in October), institutional accumulation, and retail momentum.

From this peak, Bitcoin entered a prolonged bear market. By June 2022, it had fallen below $20,000. By November 2022, it would reach ~$16,000 following the FTX collapse — a 77% drawdown from ATH.

November 2022. FTX, one of the largest global cryptocurrency exchanges, collapsed in a matter of days after CoinDesk published a report revealing that Alameda Research (FTX's affiliated trading firm) held a balance sheet dominated by FTX's own FTT token. A bank run followed. FTX suspended withdrawals. The exchange filed for bankruptcy within a week.

FTX founder Sam Bankman-Fried was arrested, extradited to the US, tried, and convicted of fraud and conspiracy. Approximately $8 billion in customer funds were missing. Bitcoin fell to ~$16,000.

The FTX collapse was the most significant argument for self-custody in Bitcoin's history: not your keys, not your coins. Every Bitcoin held on an exchange is an unsecured creditor claim. Hardware wallet setup →

June 2023. BlackRock, the world's largest asset manager (~$10 trillion AUM), filed a spot Bitcoin ETF application with the SEC — a move widely interpreted as a signal that institutional demand for Bitcoin exposure was undeniable. BlackRock's iShares had a near-perfect ETF approval record historically.

This filing triggered a wave of similar applications from Fidelity, Ark Invest, Invesco, VanEck, and others. Bitcoin's price rallied from ~$25,000 in June to ~$45,000 by year-end on ETF approval speculation.

January 10, 2024. The SEC approved 11 spot Bitcoin ETFs simultaneously, including products from BlackRock (IBIT), Fidelity (FBTC), Ark/21Shares, and others. Trading began January 11. In the first week, the combined products saw billions in volume. BlackRock's IBIT became one of the fastest-growing ETFs in history, reaching $10 billion in assets within weeks.

This represented the first time US retail and institutional investors could gain spot Bitcoin exposure through a brokerage account without self-custody — democratizing access while also concentrating large amounts of Bitcoin in ETF custodians.

April 20, 2024. The fourth Bitcoin halving occurred at block 840,000. The block reward dropped from 6.25 BTC to 3.125 BTC — approximately 450 new BTC entering circulation daily, down from 900. This was the first halving to occur with spot ETFs active in the US market, significantly increasing institutional demand at exactly the moment new supply was halved.

Historical pattern: each of the prior three halvings was followed within 12–18 months by a new ATH. The 2024 halving's post-halving window extends into 2025–2026. Price cycle context →

Next halving: approximately 2028 (block 1,050,000). Reward will drop to 1.5625 BTC.

January 2025. The 47th US administration issued an executive order directing a working group to evaluate digital asset policy, including the concept of a US Strategic Bitcoin Reserve. This represented the first time a US administration had formally engaged with the idea of Bitcoin as a national reserve asset.

SEC leadership changed, with the new commission signaling a shift from enforcement-first posture toward framework development. Congressional bills were introduced addressing stablecoin regulation, digital asset classification, and Bitcoin custody rules for US banks.

Senator Cynthia Lummis (R-WY) introduced the BITCOIN Act (Boosting Innovation, Technology, and Competitiveness through Optimized Investment Nationwide), proposing that the US government acquire 1 million Bitcoin over five years and hold it for a minimum of 20 years as a strategic national reserve. The bill drew parallels to gold reserve policy and framed Bitcoin as a long-term dollar diversification asset.

The bill faced significant opposition from other senators and the Federal Reserve. Its passage prospects remain uncertain as of 2026, but its introduction marked the first formal legislative proposal to make Bitcoin a national reserve asset at scale.

As of 2026, Bitcoin is navigating the post-2024-halving cycle. Following the pattern of prior cycles, the 12–18 months after each halving have historically produced new all-time highs. The current cycle has the added variable of active spot ETF products, institutional treasury allocations, and federal policy attention unprecedented in Bitcoin's history.

Price movements in this period reflect a market in tension between strong structural demand drivers (halving supply shock, ETF inflows, strategic reserve discussions) and macro headwinds (dollar strength, interest rate environment, regulatory uncertainty). This is consistent with every prior cycle.
