I think there is a high probability that at the end of the first stage of pre-sale, we will see the news about the start of a bounty campaign.
This will depend on the need for additional advertising. If tokens are sold in full, then there will be no need in the bounty campaign.
But to promote the game, the bounty campaign will be useful anyway. If a bounty campaign is launched for this purpose, it means that it will be launched towards the end of the ICO.
