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.
