Bitcoin was created as a native solution that could be used as a means of payment, instead of relying solely on fiat and other payment systems. Bitcoin wasn't created to threaten the existing financial system; in fact, I never imagined it could threaten the very existence of banks, which handle millions of financial transactions every day.
Bank will still exist, even if governments adopt and legalize crypto. Each has its own target market, and this depends on the needs. Not everyone understands crypto, so they will still choose banks, while others who are dissatisfied with banking services will turn to crypto for a better experience. Banks and crypto will coexist, that's what the future holds.
Didn't Satoshi himself say that Bitcoin can "scale larger than the VISA network"? And didn't he create Bitcoin as a result of banks' failures (Great Financial Crisis of 2008)? This shows us Bitcoin WAS created to threaten the existing financial system. It's just that people are now using it as a store of value instead of a currency. We can blame mainstream media with its propaganda for this.
Now that "Wall Street" is in the game, it's too late to change people's perception of Bitcoin. To top it all off, institutions, centralized exchanges, and governments hold most of the circulating supply. The traditional financial system has been deeply integrated into Bitcoin. How will the pioneer cryptocurrency by able to overcome banks this way? I'm afraid Satoshi's dreams will never be fulfilled. Banks will only get bigger and stronger than ever. You have been warned.
