Happy Birthday to the Bitcoin Whitepaper which turns 18 today! From an idea on a mailing list to an asset held by public companies, funds and governments. The journey the big B took to get here was full of ups and downs but is magic internet money starting to grow up?
From humble beginnings
Bitcoin began life as a nine-page paper. In the middle of the 2008 financial crisis, someone using the name Satoshi Nakamoto shared “Bitcoin: A Peer-to-Peer Electronic Cash System” on a cryptography mailing list. It described digital money that people could send to each other without a bank in the middle.
On 3 January 2009, Satoshi mined the first block, known as the genesis block. It carried a headline from that day’s Times: “Chancellor on brink of second bailout for banks”.
Nine days later, Satoshi sent 10 bitcoin to developer Hal Finney in the first Bitcoin transaction.
For a while, bitcoin had no real price.
That changed on 22 May 2010, when programmer Laszlo Hanyecz paid 10,000 bitcoin for two pizzas. Bitcoiners still celebrate it every year as Bitcoin Pizza Day.
Bitcoin’s turbulent childhood
The early years were messy, and the story isn’t complete without them.
Silk Road, a dark web marketplace that launched in 2011, was one of the first places bitcoin was used at scale. It gave Bitcoin a reputation that took years to shake off. The FBI shut the site down in October 2013.
In February 2014, Mt. Gox, once the world’s biggest bitcoin exchange, halted withdrawals and collapsed. Hundreds of thousands of bitcoin belonging to customers were gone, and creditors waited a decade for repayments to begin. The lesson stuck: if someone else holds your keys, you’re trusting them with your bitcoin.
There were arguments inside the community too. From 2015 to 2017, the “block size wars” split opinion on how Bitcoin should scale. They ended in August 2017 with the SegWit upgrade and a split that created Bitcoin Cash. And there were brutal boom-and-bust cycles, including the 2022 collapses of Terra and FTX, which shook trust across the whole industry.
Building on the shoulders of giants
As Bitcoin grew, people wanted it to do more than move coins from one wallet to another. Bitcoin changes slowly by design, so builders started adding new features on layers around it instead.
Two of those layers went live in early 2018.
In January, Rootstock launched as a smart contract platform secured by Bitcoin miners through merged mining. Developers could now build apps such as lending markets and stablecoins with Bitcoin’s security behind them. Today, a majority of Bitcoin’s hashrate also helps secure Rootstock.
In March 2018, the first Lightning Network software went live on mainnet, so people could send small bitcoin payments almost instantly for a tiny fee.
Companies and countries join the party
In August 2020, MicroStrategy (now Strategy) started buying bitcoin for its corporate treasury. Many others followed. Public companies now hold about 1.3 million bitcoin between them.
In September 2021, El Salvador became the first country to make bitcoin legal tender. It walked part of that back in 2025, making bitcoin optional as part of a deal with the IMF.
Other countries took quieter routes. Bhutan built up bitcoin through state-backed mining, and in March 2025 the United States set up a Strategic Bitcoin Reserve, starting with bitcoin it had seized in legal cases.
The biggest shift came in January 2024, when US regulators approved spot bitcoin ETFs. Pension funds, wealth managers and everyday savers in the US could now hold bitcoin through a normal brokerage account.
Is Bitcoin entering its “awkward age”?
Eighteen is an odd age. You’re an adult on paper, but you’re still working out who you are. Bitcoin is in a similar place.
Its foundations keep getting stronger: more hashrate securing the network, more institutions holding it and clearer rules in more countries. But its price can still swing like a teenager’s mood, and short-term moves often tell a different story from long-term progress.
Bitcoin’s first chapter answered one question: can a digital asset become money? For a growing list of companies, funds and governments, the answer is yes. The next question is what happens once it has.
History gives a hint. Gold didn’t stop at being a store of value. It became collateral, central bank reserves and the base for lending and derivatives markets. Bitcoin is starting down the same path, as companies and lenders begin to use it rather than just hold it. Unlike gold, though, Bitcoin’s supply is capped at 21 million.
As RootstockLabs’ Tony DiCarlo puts it, “financial innovation can create additional claims on Bitcoin, but it cannot create additional bitcoin.” This phase is about the plumbing: custody, risk management, transparency and infrastructure that institutions can check for themselves. That’s the work we focus on at RootstockLabs.
Read the report: Bitcoin’s Awkward Age
Tony’s new report, Bitcoin’s Awkward Age, looks at this shift in more detail. It covers why Bitcoin’s stronger fundamentals haven’t yet shown up in how the market treats it, how successful monetary assets pick up new uses over time, and what that could mean for an asset whose supply can’t grow.
Tony presents the report at the Bitcoin for Corporations Symposium in Amsterdam on 4 November. Download Bitcoin’s Awkward Age.

What does “Bitcoin’s awkward age” mean?
It’s the idea that Bitcoin is moving from an asset people mainly buy and hold to one that is used inside the financial system, while its price still behaves like a teenager’s. Tony DiCarlo’s report of the same name explores what that means.
