I don't think that Bounty will die so easy. How are they going to advertise themselves? Bounty is the best for them and it is the cheapest, because they pay only part of the money raised.
maybe they can say that this is the end of the bounty, but for me I can say that as long as there is a project and they want to promote it, they will put up a reliable team and the manager will then form a bounty to promote it, then it will still continue and will not die.
