nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s you seem knowledgeable, honest question, I need someone to explain the difference between crypto and bitcoin. It wasn't that long ago that video cards were sold out world-wide because using video cards to generate crypto was a popular and profitable thing at the expense of the environment directly.

Crypto is synonymous with scams. What's different now? How is it going to be sustainable and also not bad for the environment?
