Start first to find trusted manager who will run your bounty campaign then the rewards will escrow with bitcoin and ethereum for security
Then of course better to have affiliate program like every refer of users they will earn more still it depends on your plan like if this with future here in crypto then this is good to promote to become popular like high possible that this will happen
I guess it is not about the amount of reward, because it is not problem to get a little reward and the token has a potentiality and can grow a lot when the token has listed on the exchange that the bounty hunter get a huge amount of token but the value of the token is so cheap, even they will feel the work have been done by them not according to the amount of money they get.
