I feel that if Bitcoin is the "best fighter" then crypto is not looking good.
From my perspective, crypto/web3 is not decentralized. It is REcentralized.
It removes money from government/state hands and gives it to a handful of strangers running the largest pools on whatever relevant blockchain. I don't think that is an improvement.
To me they sound like the same problem. I stick with fiat because its easier and I trust the government more than I trust some random company/org running crypto miners.
