There are quite a number of Bounty sites such as have been mentioned already, reason I won't be stressing them any further. The real question is, of what value is a bounty campaign in a distressed market when the tokens you would receive are almost worthless. If you're going to be doing it for the accumulation of some tokens, then by all means go ahead, but if you're looking to profit from it, then just know you'll be wasting your time and effort
