In an instant it wiped out the need for another platform to launch ICOs and other stuff on. What other than Ethereum does the market needs? It can do everything other tokens can do and it has the crypto mass on board.
Definitely. It's a matter of supply and demand, and Ethereum does that what noobs want it to do, but it's solely based on speculative and fraudulent use and for that reason believe it's not sustainable. Governments are cracking down on ICO's, which won't be much of a growth factor anymore and when people are done with airdrops as well the use will decline even further. 95% of the transactions on its network isn't from Ethereum itself, but all other products which is quite dangerous actually. It means that Ethereum has nothing else to fall back on in case all other uses no longer enjoy the demand they used to enjoy.
