Ripple, I have never had high hopes for. I don't expect much out of it.

IOTA I think has decent potential for 2018 -- most likely a slight upward trend.

Stellar I would expect to be stagnant, but it is kind of a wild card for me. It might take off.

I think SIA is on it's way out. I have given up on it entirely (after accumulating and mining it for nearly a year).


That being said -- your guess is as good as mine. You never know what will happen.
