Are you sure this delay is only due to the GAS problem?
they have collected a lot of funds, why are they concerned about the cost of the GAS which is not too expensive.
I checked https://ethgasstation.info, fee GAS /transfer is 12gwai ($0.047). this is already too low in my opinion. I think they have another reason, why not distribute bounty tokens according to plan. are they afraid prices will dump when tokens are distributed?
