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.
This flow of fraudulent ICO projects and altcoins will never end, every time the market starts to recover and grow, a new portion of projects from scammers will be created immediately
Soon it will end the same as before the wave of scam cloud minings. People have already learned that before investing money, they must check the project carefully. I think that just education will make Ethereum this year the best-growing project on the cryptocurrency market.
