Cryptocurrency has a shorter history than any other kind of money, yet it already packs in a brilliant idea, the first pizzas bought with bitcoin, spectacular bankruptcies and recognition from major financial firms. In this lesson, we'll trace the path from the first experiments with digital money to Bitcoin ETFs and figure out why the market works the way it does.
- Bitcoin launched in 2009, but attempts to create digital money go back to the 1980s.
- In 2015, Ethereum turned the blockchain from a "coin ledger" into a platform for applications.
- Exchange and project collapses have wiped out people's money more than once, so caution here isn't paranoia, it's basic hygiene.
- Since 2024, Bitcoin has traded through exchange-traded funds, and crypto laws are appearing around the world.
Before Bitcoin: digital money that never took off
The idea of electronic money is older than the internet as we know it. Back in the 1980s, cryptographer David Chaum came up with a scheme for anonymous digital payments, and in the next decade his company, DigiCash, tried to sell it to banks. The system worked, but it relied entirely on one company: when DigiCash went bankrupt, the system was gone too.
Next came projects that never launched but put forward plenty of ideas. Adam Back invented Hashcash, an anti-spam measure that makes the sender do some computational work. Wei Dai described b-money, and Nick Szabo came up with Bit Gold. But nobody answered the key question: how do you agree on who owes whom, and how much, without a central bookkeeper?
This is known as the double-spending problem. A digital file is trivially easy to copy, and without a bank keeping a shared ledger, nothing stops you from handing the same coin to two people at once. Bitcoin was a breakthrough precisely because Satoshi found a way out: everyone keeps the ledger together, and the right to write the next page goes to whoever has put in the most computational work.
An attempt to spend the same digital money twice. In the traditional system, a bank puts a stop to it; in Bitcoin, the job falls to a shared blockchain stored and checked by thousands of independent computers.
2008–2013: Satoshi Nakamoto and Bitcoin's early years
On October 31, 2008, at the height of the financial crisis, a person or group using the pseudonym Satoshi Nakamoto published a nine-page description of Bitcoin. The network went live on January 3, 2009, and its very first block, known as the genesis block, had a headline from the British newspaper The Times about yet another bank bailout embedded in it.
For its first few years, Bitcoin was a hobby for enthusiasts. On May 22, 2010, programmer Laszlo Hanyecz paid 10,000 BTC for two pizzas. It's considered the first purchase of real goods with bitcoin, and the date is still celebrated as Bitcoin Pizza Day. Around 2011, Satoshi went silent, and nobody knows who he is to this day.
The first alternative coins showed up around the same time: in 2011, Litecoin sped up block creation, and Namecoin tried to store domain names on a blockchain. You'll learn more about what cryptocurrency is and how coins differ from one another in the neighboring lessons.
In 2010, two pizzas for 10,000 bitcoins seemed like a fair deal: the coins were worth next to nothing. Today the story is a reminder that a crypto's price is set by demand alone and can change a thousandfold.
2014–2017: the first crashes, Ethereum and ICOs
In 2014, the Japanese exchange Mt. Gox collapsed, even though only recently most bitcoin trading had gone through it. Users lost hundreds of thousands of coins, and the market learned its first lesson: the exchange holding your funds can simply vanish.
In 2015, Ethereum launched, created by Vitalik Buterin. Its blockchain can run programs called smart contracts, and that let anyone issue their own token in an evening. The 2016 hack of The DAO project split the network, and that's how Ethereum Classic was born.
Then 2017 kicked off the ICO era: projects sold tokens on promises alone and raised millions of dollars in a few days, often with nothing to show but a website and a slick document. By December, Bitcoin had climbed to nearly $20,000, but in 2018 prices crashed, and most ICO tokens never got a working product. Many projects turned out to be little more than a way to collect cash.
2020–2022: DeFi, NFTs and a nasty hangover
In 2020, decentralized finance took off: exchanges, loans and deposits running on smart contracts with no bank involved. In 2021, NFTs became all the rage, and El Salvador became the first country in the world to make Bitcoin legal tender. That said, in 2025 the country softened the law, and accepting bitcoin is no longer mandatory. These were the years when the word "blockchain" spread beyond programmer circles.
But 2022 turned out to be the most painful year. In May, the Terra ecosystem collapsed: its stablecoin UST lost its dollar peg, and its LUNA token became almost worthless within a few days. Crypto lenders went bankrupt next, and in November FTX, one of the world's largest exchanges, imploded.
That same year saw a very different kind of event: in September, Ethereum dropped mining in favor of proof of stake, and the network's energy consumption fell by orders of magnitude. How networks agree on new blocks is covered in our lesson on how cryptocurrencies work.
Mt. Gox, Terra and FTX all have one thing in common: people trusted their money to someone they couldn't verify. Don't keep all your funds on one exchange, and don't fall for promises of steady high returns.
2023–2026: regulation and the arrival of big money
After the FTX collapse, regulators got serious about the industry. The European Union adopted the MiCA regulation, which has applied in full to crypto companies since the end of 2024. In January 2024, the US approved spot Bitcoin ETFs, followed by Ether ETFs that summer, so you can now buy them through an ordinary broker.
In April 2024, another halving took place: the miners' block reward was cut in half again, as happens roughly every four years. In December 2024, Bitcoin broke through $100,000 for the first time. In 2025, the US passed the GENIUS Act, a stablecoin law. Thanks to ETFs, pension funds and conservative investors who would never have opened a crypto exchange account could now put money into Bitcoin.
Rules still vary widely from country to country and keep changing. Before you buy or sell, look up the current requirements where you live instead of trusting what you read on social media.

| 1980s–1990s | DigiCash, Hashcash, b-money, Bit Gold | Ideas emerged, but there was no solution without a middleman |
| 2008–2009 | Bitcoin is described and launched | The first money with no central issuer |
| 2015 | Ethereum launches | The blockchain became a platform for programs and tokens |
| 2017 | The ICO boom | A massive inflow of money and massive losses |
| 2020–2021 | DeFi and NFTs | Financial services and digital ownership without banks |
| 2022 | Terra and FTX | Trust collapsed, oversight got tighter |
| 2024–2025 | ETFs, MiCA, stablecoin laws | Crypto became part of mainstream finance |
What this history means for a beginner
Over 17 years, the market has gone through several cycles: a rapid rally, euphoria, a crash of tens of percent, a long lull and then a new rally. Every time, it seemed that this time would be different, and every time, some newcomers bought at the very top and panic-sold at the bottom.
The second pattern is about trust. The Bitcoin network has been running since 2009, and the few serious bugs in its code were found and fixed quickly. Meanwhile, the exchanges, lenders and high-profile projects around it have collapsed with some regularity. Don't confuse the technology with the companies that make money from it: they carry different risks, and coins in your own wallet are protected very differently from coins in an exchange account.
Finally, regulation is getting tighter. That's inconvenient for anyone used to full anonymity, but it gives ordinary people more protection: exchanges verify their customers, hold reserves and report to regulators. How this works in different countries is covered in the course level on regulation.
- Don't buy on emotion after big headlines about record highs: history shows that a peak is often followed by a deep correction.
- Check who's holding your coins, and don't keep everything in one place.
- Treat promises of guaranteed returns as a red flag, not an opportunity.
- Remember that past gains guarantee nothing about the future.

FAQ
Who is Satoshi Nakamoto?
It's the pseudonym of Bitcoin's creator. Nobody knows who he really is: several people have claimed to be Satoshi, but none has offered convincing proof. And the coins believed to belong to Satoshi have never been moved.
What was the first cryptocurrency?
Bitcoin, launched in January 2009, was the first decentralized cryptocurrency that actually worked. DigiCash and other forms of digital money came before it, but they depended on a single company, and when that company went, so did they.
What is the Bitcoin halving?
It's a cut, hard-wired into the code, that halves the reward miners get for a new block. It happens every 210,000 blocks, or roughly every four years; the most recent one was in April 2024.
Could history repeat itself and the market crash again?
Yes. The crypto market has seen deep crashes more than once, and they can happen again. That's why beginners are better off starting with a demo account or small amounts and picking up the basics of risk management along the way.
