Before Bitcoin
Bitcoin didn’t appear from nowhere. Through the 1990s and 2000s, cryptographers known as the cypherpunks tried to build private digital cash. David Chaum’s DigiCash, Adam Back’s Hashcash (proof-of-work to fight email spam), Wei Dai’s b-money and Nick Szabo’s bit gold each solved part of the puzzle. None solved it all, until Satoshi combined the pieces.
The birth (2008–2010)
The whitepaper
In the middle of the global financial crisis, Satoshi Nakamoto shares “Bitcoin: A Peer-to-Peer Electronic Cash System” on a cryptography mailing list.
The genesis block
The first block is mined. Embedded inside is a newspaper headline: “Chancellor on brink of second bailout for banks”: a timestamp, and a statement of purpose.
The first transaction
Satoshi sends 10 BTC to cypherpunk Hal Finney, who had tweeted simply: “Running bitcoin”.
Bitcoin Pizza Day
Laszlo Hanyecz pays 10,000 BTC for two pizzas: the first known purchase of real goods. Bitcoiners still celebrate it every year.
Satoshi steps back
Satoshi’s last public forum posts are made in late 2010, and by spring 2011 they disappear entirely. Their roughly one million early coins have never moved. Bitcoin carries on without its creator, which is arguably its most important feature.
Growing pains (2011–2016)
Silk Road
An online black market uses bitcoin, bringing notoriety and a lasting (and outdated) reputation for crime. It is shut down by the FBI in 2013.
The first halving
The block reward drops from 50 to 25 BTC, exactly as the code dictated four years earlier.
Mt. Gox collapses
The exchange handling most of the world’s bitcoin trading loses around 850,000 BTC to theft and mismanagement. The lesson is burned into Bitcoin culture: “Not your keys, not your coins.”
The second halving
Reward drops to 12.5 BTC.
The block size wars (2015–2017)
As usage grew, blocks filled up and fees rose. One camp, backed by many large companies and miners, wanted to make blocks much bigger. The other argued that bigger blocks would make running a node too expensive for ordinary people, centralising control.
The decisive moment came from users. Through the “UASF” (user-activated soft fork) movement, people running their own nodes made clear they would only accept blocks following their rules. The smaller-block side won: SegWit activated in August 2017, and the big-block supporters split off into a separate coin, Bitcoin Cash.
Why it matters: the block size wars proved that people running nodes (not companies, miners or developers) have the final say over Bitcoin’s rules. That’s why running your own node matters.
Going mainstream (2018–2023)
Lightning Network goes live
A “layer two” for instant, nearly free payments launches on mainnet, letting Bitcoin scale without bigger blocks.
The third halving
Reward drops to 6.25 BTC, just as central banks print trillions in response to the pandemic.
Corporate treasuries
MicroStrategy (now Strategy) begins holding bitcoin as its main treasury asset, kicking off a wave of public companies following suit.
El Salvador
The first country to make bitcoin legal tender. (In 2025, as part of an IMF agreement, accepting it became voluntary for businesses.)
Taproot
The biggest upgrade since SegWit improves privacy and flexibility for more advanced wallets like multisig.
FTX implodes
Another giant exchange collapses with customer funds missing, and another wave of people learn to withdraw to their own wallets.
The institutional era (2024–today)
US spot ETFs
US regulators approve spot bitcoin ETFs, letting pension funds and brokerage accounts buy exposure. They become some of the fastest-growing funds in history.
The fourth halving
At block 840,000 the reward drops to 3.125 BTC.
$100,000
Bitcoin crosses six figures for the first time.
A US Strategic Bitcoin Reserve
A US executive order establishes a reserve made up of bitcoin the government already holds from forfeitures.
New all-time high & a heated debate
Price peaks around $126,000. Around the same time, Bitcoin Core v30 loosens limits on extra data in transactions (“OP_RETURN”), sparking fierce debate and a surge in nodes running the alternative software Bitcoin Knots.
A hardware wallet wake-up call
A long-hidden randomness bug in some Coldcard firmware lets attackers drain thousands of wallets. It’s a painful reminder to verify, diversify and consider multisig.
The fifth halving
At block 1,050,000 the reward will drop to 1.5625 BTC. Track the countdown live on the dashboard.
What history teaches
- The rules hold. Through crashes, bans, hacks and civil wars, the 21 million cap and the issuance schedule have never changed.
- Custodians fail; Bitcoin doesn’t. Nearly every big loss came from trusting a third party. Self-custody is the antidote.
- Users decide. Node runners, not corporations, ultimately enforce what Bitcoin is.
- Volatility is normal. Past cycles have brought drops of 70% or more, followed by new highs later. Patience and understanding beat timing.
