Ethereum is over.
We have seen why Ethereum cannot scale in 2017, even a crypto kitty joke coin could make it grind to a halt.
Ethereum has many attack vectors.
I am selling all 2,000 ETH for BTC and DIECI when it launches. I predicted ETH when it was at $1 and bought many, I'm not proudly professing that ETH will go to $50 by 2019, and DIECI will take 60% of Ethereum's market share.
I think it is not that simple that announcing the end of a coin, which has the best cap according to all other altcoins. In my opinion, ethereum is still a strong coin which can rise again.
