but you won't find this at the top of HN because vast majority of HN hates crypto-currency, most likely because it was once cool now it's more mainstream so it's not cool anymore. What a shame.
Comments like the one you've posted here are a key factor in the negative reaction to blockchain posts on this site (and in general).
I think people hate the Alt-coins pump and dump schemes.
With the exception of Ethereum and Monero, the rest are entirely speculation IMO.
I hope crypto solves a problem, but there will be a lot of people losing money because they got caught up in the $$
