Yeah, the problem is that he/she didn't link the bounty project here. So I have my doubts here, specially giving out 71 ETH? You just show us the wallet address here, you can just get any wallet address out there and claim that it came from a certain project.
So just to be clear here, I have my skeptics until this is proven. You'll just putting some hype here, specially those newbies who join bounties after bounties. Maybe you are giving them false hope, just saying.
It is doubtful really but it also is possible. If we dig and investigate further we might find the truth. I was a bounty hunter for years but I never had the chance to get that certain amount in just a single campaign. May this was just some wallet transfer between the manager and the devs.
