It depends on how it's price will move but it is very likely that you will not be reach after holding that for 1 year, I think crazy price movements will not be seen for a while. Still it is a good investment but If that was your whole stash then I recommend you not to put it all in ETH. That way, there are more chances for profit, and you won't regret your decision if ever ETH goes sideways for one whole year.
