Many bounty projects scammed us, but I think there has some legit project to continue the bounty job. I am still learning how to find a better project until then I will follow big people and will do what they do.
Always use your research on every project and bounty, because that will obviously help you also from scams, because following people who are big alone will obviously not be enough for you to avoid the scam of projects or bounties.
Actually there are handful of bounty projects that are coming out this year than in the previous years and they are actually doing quite good like Cartesi which is currently featured in Binance Launcpad. Bounty Detective has some quality bounties as well and some others too. You only have to make a proper research to avoid those red flags bounties to get rewarded.
