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? 
Those shit projects are idiotic persons who did run those fake materialistic. Exchange didn't work, coins didn't work, etc... They just create a temporary coin just to get some extra btc or eth to invest. How damn they are really bad. Pity us who work so hard just to buy coins.
