It is the matter of choice mate buy Bitcoin so that you won't worry no more. Scam in cryptocurrency is different from fiat money. Centralized scam is different from decentralized scam what's interesting here is that cryptocurrency could possibly be a tool for us to have financial freedom unfortunately not in fiat money due to bankers and powerful entities that controls the world's economy. In fiat people who are poor become poorer unlike here in crypto industry where we can be one of the millionaires one day regardless of social status.
