There are many good low priced altcoins which are below 1$. They are XVG, RDD, Pura, Sia coin, all these are below 1$ and can give decent earnings in long term. Do your own research also before investment.
It is impossible to predict x100, not even x10 ovbiously. That would be way too easy.
I own reddcoin and verge and hope you are right.
Some of the coins mentioned here have the potential to go 100x. Many could not in normal circumstances.
Lets focus on x5 maybe x10.
In that case many coins are eligible
I can say which coins can't go x100 in short time of a few months. Those are coins which need many billions of investment to do so.....x100 is a lot dude.
For that kind of returns you should look at coins which are shitcoins at the moment you buy them and take the jump of faith.
Many people became millionairs with verge......many sold before the rise thinking it won't do it. Others like me joined later and are waiting for it to rise again, i'll be more than happy with x10 lol

If you bought some of the good coins now, you woould make 100 or 10.000x . I can't name all but indeed verge, neo, deepunion, prl , railblocks and many coins in the last year.
I can't see any major contender for the same profits at the moment. icos are expensive in my opinion, some seem to be utterly bullshit coins ( yet people buy them lol ).
I would concentrate on coins which are more or less established, unless you are a investor and have butget which you can lose. In that case choose 10 or 20 coins and put in 1000$. if some of them make x10 or x 100 you did well. If one does x1000 you are happy lol
Choosing 1 or 2 coins for x100 is way too hard
