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.
Vitalik Buterin did the mistake of his life by pannicking about people panic selling and demanding that exchanges froze the ETH markets... I mean what the FUCK? Think about this for a moment. This is terrible and sets a scary precedent. This would never happen with BTC because everyone knows it would be a disaster.
Further there is no one who could demand this there is no Lenin with his minions following him
