It would be a good idea for the OP to generate dedecated adresses to the bounties so people can easier donate directly and he handles the coins.
It's also kinda hard to figure out how much bounty is for an retailer atm and just because someone says he's going to plege means nothing if you don't know him.
would be very useful, if there are donation addresses we can see how much is donated, but does require trust, escrow?
If you don't trust the developer you can't trust his crypto either so I belive escrow is not required at all.
