How many successful projects with such reward paid hunters since 2018 that you know?
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.
Correct out 100 bounties only one project is paying giid amount of rewards to every bounty hunters, thats why always make a research before joining in a bounty campaign.
