I have done some bounty campaigns that were unsuccessful.. Also some were scams. But I have received some tokens from few of that projects. So I need to know this, Is there any opportunity that can I use this tokens?

I think ku shoukd just hold them up and wait for it to be lricey this year becaise its the bullrun we are talking about. I think its the latter to just give up and leave it around. just invest on another coin and leave the shit one for a while
