Money is whatever people decides holds value. Doesn't matter what it is, seashells, gold, beanie babies, paper. Currency is just a faith based system. Fiat is a complete scam but most people are too stupid to realize or lack any real fight to go against the banks.
Correct. Banks printed a lot of money for the rich people only and poor people become poorer. Fiat does not favor people living in the lower status in the society. Money can be printed but it is a centralized one so it won't last as people prefer a decentralized one that will potentially give them financial freedom in the future. Cryptocurrencies has value so we can use it like what fiat can do but more than that crypto is more convenient than fiat.
