seems it is impossible these days, $350k for the bounties is too much I think because most of high rewards are scam projects. Low rewards can be legit but for the high rewards it can be scam, still you need to research first so that you know.
You are absolutely right! High reward means scam nowadays! This year, only RideNode has 350K USD allocation for their bounty campaign and at the end, they scammed as usual! So, running for the high reward-based campaign is not a good idea anymore, rather run for quality! All the quality bounty campaign has a limited budget with the limited slots!
