Every investment in Cryptocurrency is all risky, if you are afraid of investing because you are afraid the price will go down, you will not be investing. Remember, the price of Cryptocurrency up and down is normal, when it rises in one day the price goes down we also can't know it. Likewise with Ethereum, but if I think Ethereum is a good coin, a strong coin. So buying Ethereum in my opinion is highly recommended, rather than buying a new coin that is not certain good or bad.
