Etheruem is no doubt a coin to hold for the long run. The rise won't surprise me because bitcoin is about to start a move upwards, so it is normal with experience. Most coins tend to wake up when bitcoin do.
well to be frank i really doubt it because too much problem happened with it already.
from the nodes kept shutting down,a huge storage for synchronization and less development.
lately we could see many project created based on NEO,that means NEO might be the next generation of Ethereum itself.
it was a cycle,i am absolutely sure if nothing happens with it for a year or two years later with Ethereum.
NEO might replace ETH,it's ETH competitor and we can see it right now,many project was created based on it daily on the other hand ETH kept doing nothing(basically).
the only problem was it's centralized at this point.
just remember when LTC was Silver and Bitcoin was Gold back then,afterward ETH popped out and replace LTC.
