When he says it is "Going to work" I'm wondering really what he is talking about. Etherium doesn't actually do anything.
How many years does it have to be out until at least 1 DAPP actually does something?
STEEM and BitShares are the only blockchains where you can actually do something other than just speculate on a coin.
Could someone still make money on Etherium? Sure. There is a lot of dumb money dumping into this stuff. Someone will ultimately be the bag holder just like there will be bag holder in Twitter and Snapchat. There have been bag holder in STEEM but at least this blockchain actually has a usable product that works. Not just pie in the sky.
