Hold it. It will surely follows bitcoin price and will be second to bitcoin in terms of marketcap.
I agree for that also, hold it for a long term so that in return you will see how would it pumps like bitcoin, we now that eth is more precious among others and it is the one who can reach the btc price as speculated.
In martketcap there's no reason for the coin not to pump as long as it will more helpful and meaningful ccoin with the high value also.
