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.
Ethereum are continue there services and it is now a widely use that people choose this coin to invest with and they really appreciate the Ethereum backs and Ethereum will me more popular someday next to bitcoin coz coinbase now are featuring Ethereum so that they can easily pay credit card to ethereum
