Yes of course Ethereum will rise again, but not in a long time. And you will have grown tired of crypto before that happens. We all got to watch every single one of the useless ICOs die first, and then all the ALTCOIN projects, and after all of this we can see the start of a new bull run on crypto.
It seems to me that Ethereum has already started rising. Let us wait a bit - for several months more, and we will get the profit from this best altcoin. I am also going to invest more in ETH this year.
