HN usually has lots of negative comments - some of them are even constructive negative comments. It's not necessarily a bad thing. I come here to read these intelligent criticism.

Besides, I don't think it's particularly more negative on cryptocurrencies - go to any other internet forum (that are not specialized in cryptocurrencies) and I think you'll find a similar mixture of opinions.

Finally, "Google also invested in X" isn't a very good counter-argument here. Have you seen some HN comments when Google is being discussed?
