what if one bounty, we do not receive a fair share, have you ever experienced it?
Are you referring to the number of stakes given? If that's the case, then I don't think there is anything unfair here. Stakes are rank based. The higher the rank, the higher the allocate stakes. I have nothing against this because high ranking forum members were here way before us. And so we should give them credit for that.
If you're referring to a bounty that had some miscomputations on the stakes, then you should get the attention of the bounty manager. It is easier to catch them on the project's Telegram channel.
