Oddly, HN is over all rather closed minded about cryptocurrencies/blockchain. I can understand being jaded at all the bitcoin maximalist out there that are frankly ignorant or even just being generally weary about the idea of such currencies... but it seems like the general sentiment is very negative in almost every thread with very minimal understanding of cryptocurrencies or frankly currencies in general.
Shame, tbh. I wish there was better discussion on the topic. Blockchain is very cool, even if you don't believe bitcoin is replacing your dollars ever.
