I think ETH was in trouble before. This just adds to the already big trouble it is in.
It is not near as fast as Steem or EOS. To build games, transactions cost every time. To run apps, the chain is near capacity at all times. Trying to switch to POS while maintaining activity... all of this is not good for ETH. Next generation chains like ADA, EOS, TRON etc... will also take away from ETH. With BTC now adding RSK, ETH is not growing in cap IMO, likely shrinking.
