you do realize that when fiat is backed up by nothing they can just print it at will,
Since you can't just print bitcoin and the supply has a cap, then your arguments here are moot.
so you might need to gamble some of your money in the crypto markets maybe buy some bitcoin and hope it goes "up".
That is irrelevant. There are always people who are gambling on anything including the direction wind is going to blow! The fact that bitcoin as a currency provides many utilities that gives it value and it doesn't need to be backed by anything.
