There is no doubt that bubbalex is a good bounty manager, also he is a reputed manager. He always tries to bring the legit bounty. But some managers don't look at the project. One thing is different from other managers, he always takes care of bounty hunters and updates the spreadsheets on time.
I think that if you were a bounty manager, you wouldnt look at the project either, but would just make money. bubbalex is simply the only one who cares about his reputation.
Bubbalex is not only caring of his reputation but he also care about the participants to his bounty and that is why he goes for top projects so that hunters too can benefit from the labour.
And with limiting participants, he gives ample benefit to those who are lucky to join.
Indeed, he was very interested in the bounty hunter. That is why he always limits participants to ensure their interests. Most of his campaigns are successful and get people a lot of money, DIA has been successful lately and I think this is the best bounty this year.
