High rewards in bounty campaign is still possible. But the number of such bounty campaigns is less now. Because most successful project are not paying bounty hunters. In some bounty campaigns, bounty hunters are paying less, such as Digitalbits, ARCC. However, there are still some bounty campaigns in which high rewards are possible such as PZM cash, AZM, Dexacoin, Sudan Gold Coin, YOUengine, Oikos etc.
