The Ethereum alt coin is just a fad. People are passionate about it because they can mine it at home with graphics cards and earn some cash while it offers the highest profit of all the alt coins right now. After Ethereum switches to PoS or it becomes unprofitable people will just look around and go to the next pre-mined alt coin investing their cash in a pump and dump scheme until said alt coin is bone dry and everyone will move to the next. Rinse and repeat. Oh and by the way I think Vitalik has already started selling his ETH stash so do you think this fact inspires more trust in the system or it is just an elaborate pump and dump scheme?
