In the traditional financial system, your money is actually controlled by the bank. They can freeze accounts, restrict withdrawals, and review transactions—you think it's your asset, but it's just a string of digital records.

Bitcoin and the entire crypto world have changed these rules of the game. With a private key, you truly own your assets; no one can freeze them, and no one can forcibly control them. This absolute control is precisely the core purpose that Satoshi Nakamoto designed Bitcoin for.

From custodial banking to self-custody, it sounds like a small change, but in reality, it is a fundamental shift in financial discourse. That’s why some say that the greatest value of cryptocurrencies is not speculation, but the true return of financial autonomy, which was monopolized by centralized institutions, back to individuals.
