My question is why?
You go after return/growth...since you can get fractions of a coin, it doesn't matter what their price is.
Most cheap coins are cheap for a reason...unless they are really new that you know is good, stir away from them.
I think you're right, the cheap altcoin is hard to grow in and even it can disappear.
There is no reason for us to invest in things that are too risky.
