The right choice, because it seems to me that this cryptocurrency is the most valuable in the market, the rest I do not think that will show such growth as Ethereum. He is more promising than Bitcoin since on his network many projects are created to improve the real world and many areas and directions.
You are right and Ethereum is going to recover to the last peak. I don't thing that Ethereum is more promising than Bitcoin, but definitely has a great future and it is under valuated now.
