Probably quite a lot of bounty participant would be willing to "pay" half of their Envion bounty score to some "savior" lawyer if he could guarantee a win. But I am not sure how would that be done haha, winning the case would then have to be a condition of getting paid, if not - pro bono

Dream on.
I hope people are dreaming about the Envion payments if a project doesn't have any product and people who are behind it, even though we get payment it doesn't help us to make money. A project should always have an active working product and it will surely help us to hold the coin in the long term. I don't have any faith in this project.
Envion is proven scam maybe this guy is not aware of the status of this project than this should be the reason why he still have dreams about the comeback. There was active claiming campaign but don't know what happen to this and this project is dead.
indeed, in my opinion just leave it, why think of envion that is clearly proven to be a scam!
If they want to distribute tokens to bounty hunters they should have picked them up in a spreadsheet in the bounty thread
