I don't think any coin can 100x unless nobody knows about it nowadays especially with all these regulations that will happen in 2018, but for a nice 5-10x coin I think prl is a possibility, 10x would put it at a 1 billion market cap which is highly unlikely imo.
One of the coins nobody knows about yet is Marinecoin. Right now you can get a lot of free coins in the free ICO. Check here:
