Actually I'd never expect that Altcoins will totally grow.I'm so much fun to find what is the best fit to make my investment grow.. As of now I choose ETH, Dodge Coin and BCH as my longtime profit for an investment.
Altcoins now have their path because there are so many different networks that have sprung up so far, they are no longer dependent on other coins. Maybe the other you say is DOGEcoin? I didn't even include that on my list for many reasons. And another BCH that has also been silent for a long time, is no longer overlooked after the 2017 bull run. You chose that and it's just my opinion.
