Are you in profit if you're going to sell those tokens even if it's little? well, if you got those tokens for free from their campaigns, it's all on you if you're going to dump it all.
IMHO, you need to take action before its volume drops some more.
I have no further decisions to make for now, because if I sell all those tokens I only have too little profit to acquire. With respect to the volume drops, of course there's fear about it and it's only by case to case basis. That sounds worrisome, yet I have to battle those emotions rather than wasting for none.
If I'm on your situation I might also feel the same and regretting if I'll sell at a little profit. But if after a few days or weeks then there's still no movement on its price.
I'll have no choice but to be happy with that little profit.
