I think ethereum still have a chance to be altcoin people choice because until now, we see in the market, the ethereum price is up and down too oftern and i think ethereum is still have a fans. ethereum itself is a good alt and we can make invest with ethereum but not for long time.
Even if you are not planning to trade with Ethereum, you should better keep these coins in your wallet. You might use ETH cryptocurrency for participating in ICO projects, for instance. 25% of my coins are ETH.
the best way to keep getting profit even though eth is decreasing is by investing coins in ico, because with investment we can get big profit and make our eth count increase.
