Crypto was invented as a fully decentralized form of keeping and spending money, not as an “investment” (really, gambling) instrument as it is used now, so I fully agree crypto isn’t evil, it’s how it’s currently used that’s a problem. Proof-of-work though is evil, due to its energy requirements. Thankfully some coins (e.g. ethereum) are switching to proof-of-stake which doesn’t waste energy for nothing.
Proof of stake is making the crypto centralized by the stake holders, also the ethereum blockchain size is huge compared to Bitcoin, making it even more centralized because less people are willing to volunteer except the stake holders.
