Yes it is a good decision. Eth also a silver coin but Wait for some time eth price will reducing to 900$. Then you can buy or else buy now any another altcoins like ripple, sct, neo, or any famous coins keep it for a some months then sell it for profit.
I think everyone deserves it, Eth will not be $ 900 because I believe this year is a resurgence for Eth, so it's time to buy, do not wait until it goes down, because if you wait you will regret it. Going forward because Eth will increase next month.
