To correct some oversimplifications in this thread, let me just summarise some facts:
Crypto is exactly as worthless as money.
Not all crypto is bad for the climate, see for example Etherium and Solana.
Crypto has legitimate uses, especially as a replacement for traditional bank transactions, which to remind everyone, are basically made up numbers and ‘trust me bro’-s. And I will explicitly include smart contracts and NFTs here, just to annoy people who don’t get them.
Not all crypto is private. In fact, it was designed to be the opposite, hence most crypto isn’t private at all.
While not all crypto is private, even less ways to spend or exchange crypto are private. A simple and also very private thing is cash.
Afaik most people who seriously want to have a local LLM start of off a pre-trained one from the internet…?
