This is kinda an ambitious project and i am liking it. 5% bounty is way too high though imho. Lot's of free tokens coming and with the bear market going on, there could be lack of buy support.
I think the essence of bounty is for promotion of a project. It is way easier to for a project to hit the ground running with bounty participants doing the advertisements for them. 5% is not too high if you ask me though because there is a lot more a project needs to be visible in the cryptospace
