Yeah it is definitely a problem for project developers if they have to send hundreds of small transactions to the bounty hunters every week. It's very likely that the fees are higher than the actual transaction value in that case. Maybe it would be a good solution, to send only 1 transaction at the end of the bounty instead of small transactions every week
there is no need to keep sending transaction every week again the bounty campaign is already over and the team are owing bounty hunters 3 weeks payment so it is something they can send at one time but the fact is that gas fee is still very high so my suggestion is they should just use Tron network instead or lite coin or ripple this coins are very cheap transaction fee
