I think Ethereum will be no more among us after this attack, the issues to it will be fixed sooner but i don't think that it will survive for longer , it will die in this year.
I hope so 
and ethereum classic ETC will become more popular and there are many people who use it for trading, because consept of ETH has be taken by ETC. Actually ETC is real ethereum after hard fork.The Ethereum price is rising at the moment. I think it is caused by the big convention happen in Shanghai, China.
