People hyping those coins probably just missed the peak and now hope to reach this again.
I don't wanna say that they can't rise anymore, they definitely can. But if you're lucky you will see x2 or x3 if really lucky. But never x20
You are looking for a coin to invest BEFORE hype starts. But that's dangerous. You should always do your research very carefully.
Currently VIB is increasing sharply. It will probably reach 1$ soon, so at least x5 (x10 for ICO participants)
Walton also had it's hype already, but due to BTC hard fork it's quite affordable right now. If they really manage to build other sectors than clothing, you might see x20 there.
IOTA is the only coin mentioned before that has a good potential to grow, although it has already had its hype.
Next hype in November will probably be Blockstack, because they already have a lot of running apps.
This is only my personal opinion based on my own research. But as I said, always do your own research and don't trust anybody in a board (yes not even me )
Good post, agree... If you want 50x the alt coins in the billions aren't as likely going to do it for you as getting in at the ground floor somewhere else...
