I don't know too much about crypto, it doesn't really interest me and I've never bothered to find out more about it. It does seem to be some right-wing libertarian thing so reflexively I'm suspicious, but some of the claimed ideals appeal to me as an anarchist.

I refuse to invest in stocks because that would mean (potentially) profiting from the exploitation of the workers in that company. I suppose if I were awarded stocks in the company I work for that might be different, I'd need to think about it more.
