$TROLL seems to have the potential to double. But the problem is that if you get in too late, you might end up buying at the top. These small coins are highly volatile, and catching the bottom requires precision; otherwise, you'll become the bagholder. When the market is moving, the pace is very fast, and many people only realize they've bought at the peak after the fact. So if you haven't entered yet, be cautious now, and setting a stop-loss is more important than anything else. Otherwise, it can really frustrate you.
