There's something that's always been very interesting. A person named Satoshi Nakamoto changed the world with a 9-page PDF, then disappeared — 15 years with no trace. No one knows who he is.

On October 31, 2008, this name appeared on the cryptography mailing list. He published a paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System." Two months later, the Bitcoin network went live, and the genesis block was mined. Satoshi left a line in it: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" — the UK Chancellor was conducting a second bank bailout. This was not just technical; it felt like a declaration.

Over the next two years, he did almost all the pioneering work. Writing the first client, running full nodes, helping others mine, sending the first BTC to developer Hal Finney. Then in 2010, he handed everything over to others. In April 2011, his last words: "I have moved on to other things." Since then, he has been silent.

There's a number worth pondering here. It’s estimated that Satoshi mined about 1 million BTC. At today's prices, that’s worth over 100 billion dollars. But for 15 years, not a single one has moved. No transfers, no spending, as if frozen in time.

Regarding his identity, the community has long speculated. Some believe it’s Hal Finney — the cryptographer who received the first Bitcoin transaction, who happened to live near a Dorian Nakamoto. Others point to Nick Szabo, who created "Bit Gold" in 2005, with a writing style highly similar to Satoshi’s. Hashcash, invented by Adam Back, is cited in the Bitcoin white paper, making him a suspect. Some even say it’s Elon Musk or Peter Thiel. The most outrageous is Craig Wright claiming to be Satoshi, going to court over it, but never signing with Satoshi’s private key — which could have proved his identity in a second. The developer community generally doesn’t believe him.

There’s a conspiracy theory that it’s the NSA. The core cryptographic algorithm of Bitcoin, SHA-256, was indeed designed by the NSA, and the launch coincided with the 2008 financial crisis, disappearing cleanly afterward. But this contradicts Bitcoin’s original goal of decentralization, and there’s no solid evidence.

What I find most fascinating is right here. Satoshi gave the world a code, then chose to disappear. No pursuit of fame, no cashing out, no power. Perhaps that’s the most important part — Bitcoin’s existence doesn’t depend on any founder. Its foundation is mathematics, code, and community. That’s why it cannot be destroyed. Maybe Satoshi understood that once he revealed himself, he would become a risk. Staying mysterious is, in fact, the best protection for what he created.
