Well i have tried the COSS ICO bounty recently but i was a total waste got paid close to 10USD after 2 months

Why is it a total waste? When you got paid by the campaign? Maybe not that much as you expect thats why thats yor reaction afterwards.
10$ for the current value but if hold for much longer maybe value will rise more, just need to hold as it was an ico so development will take some time.
