The origin of Bitcoin is a mysterious legend.

**The Awakening of the Unknown**

In 2008, the global financial crisis swept across the world. A mysterious figure using the online pseudonym "Satoshi Nakamoto" released a paper with a surprisingly simple core idea: "We need a currency that doesn't rely on banks, that anyone can participate in, and that cannot be tampered with in the ledger." This was the declaration of Bitcoin's birth. No one expected that this idea would eventually trigger a technological revolution.

**A Ghostly Presence**

In 2009, Satoshi Nakamoto launched the network and mined the first batch of Bitcoins. He collaborated with a few geeks on forums to refine the code but never revealed his true identity—whether an individual or a team remains unknown to this day. He communicated in British English, with a bizarre and unpredictable online presence, and every technical detail was meticulously polished to perfection. Like an invisible engineer, he carefully built a parallel world in the shadows.

**A Sudden Departure**

By the end of 2010, Bitcoin's popularity began to rise, and the community became increasingly active. But at this critical moment, Satoshi sent a final email to a core developer: "Bitcoin is sufficiently decentralized now; it's time to let go." After that, he disappeared completely from public view and has never reappeared. This dramatic exit is like a martial arts master in a wuxia novel, who creates astonishing skills and then retreats into seclusion.

**The Legacy of Ideas**

What he left for the world was far more than just a digital asset:

**Trust in Code, Not Institutions** — Blockchain technology allows complete strangers to cooperate without relying on trust, fundamentally changing the logic of human collaboration.

**Currency Democratization** — He proved a radical idea: everyone can own and control their own currency, although this ideal is still evolving amid controversy.

He disappeared, but Bitcoin is like a self-replicating living idea, growing wildly around the world.

**An Answer to a Riddle**

Looking back now, Satoshi Nakamoto used Bitcoin to pose an eternal riddle to humanity, with answers involving technology, power, and freedom—three timeless topics. According to statistics, the coins he mined early on remain untouched; today, they are worth hundreds of billions of dollars, yet he remains silent—perhaps the most "advanced" form of concealment in human history.

This is a story of a mortal laying the foundation for the world and actively disappearing. What he changed was not just technology itself, but the very possibility of change.
