I have seen this discussion on Reddit where someone came with the idea that the bots will never be extinquished because if the bots will disappear then the price for the blue crystals will plummet and the legit whales will no longer have any incentive to buy gold via the royal and blue crystals conversion.
This is backed up furthermore by the fact that we received the nerfed gold rewards from dungeons even though we have a fresh economy and that change was not aimed at our version so that the players cannot maintain the price for the blue crystals by themselves among other things.
Win/Win because the bots keep the price stable for the blue crystals while the majority of players also stay poor to not make too much progress and quit too fast.
