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? 
This is the main reason why everybody needs to diversify risks, capital, efforts and so on. So many ICOs are turned out to be scam and very few are succeed... And you never know which one will be the winner, so make sure you bet on as many of them as you can afford
