And it doesn't matter will crypto replace fiat or not.
That is not about becoming rich, the question says what will happen if the fiat is ever replaced with the crypto currencies. The attitude that you brought in here is like an investor. But we need to think about it as general public as well. It could benefit us in lot more ways than what you think. (Profits)
It will help us improve the transaction system in digital way, new applications will emerge in the market all the time, and this will help the community to grow bigger and bigger always. The profits, investors, etc things will come later on.
In the era of digital currency it brought so much advantages and it creates an atmosphere of safety, security, and transparency since it's a real innovation and bitcoin is the first. On the other hand, since bitcoin is not yet widely-accepted, its economy is still young and developing, more are still doubtful and restrict its functionalities. Fiat has a central command, and has legal tender, with the rapid evolution of cryptocurrency, still it is the widely used form of exchange where most people are so accustomed with it ever since, and the larger portion of the world are still under centralized network run by government.
