Not at all. The rich get richer and the poor get poorer due to inflation, which is caused by government spending and central banks creating money out of nothing and saying that it has value when it does not. Not all crypto is extremely power-hungry. Take Monero, for example, as it is mined with CPUs only, which everybody has access to. If cryptocurrency mining ends up using less power than the banking system, then that is a net positive instead of a net negative. The majority of cryptocurrency losses have not been because of the blockchain, but because of services built on top of it that should not have existed to begin with, such as exchanges, lending companies, etc. When you give your crypto to somebody else, it is no longer your crypto, and that's where people have messed up by giving their crypto to places like FTX, Mt Gox, etc. There's also quite a lot of mistakes made with two-factor authentication via SMS which is not secure to maintain a cryptocurrency account such as Coinbase. When somebody tries to explain that you should not hold your keys on exchanges, a lot of times you get feedback about, oh, that's too much work. Well, if you're not going to care about your money, nobody else will. One of the big major points of crypto is to eliminate the trusted third party.
