every post including cryptocoin here gets a generic comment like yours about some other cryptocoin that is 'very promising'
"valid consensus mechanism that scales of PoS and PoW networks".
Half of the comments on this page complain about how Bitcoin uses too much energy and how PoW is wasteful. This is a direct (allegedly, if what they write is correct) solution to exactly that.
I follow alternative consensus algorithms and trustless decentralized app tech in the blockchain space because I think it is interesting and democratizing tech. I do not own half of the coins I follow and couldn't care less for speculation. Technologically, cryptocurrency is still an exiting domain and scepticism is in place, but the blind hate for anything blockchain on HN is a bit OTT.
