It's an interesting question. You want to register early to these and maintain a few more chips earlier so that you can cover people for bounties, because they are literally half of the tournement.
Working out the value of bounties is quite hard to do. A minimum size bounty in a progressive KO is worth half of the starting stack, because if bounties are half the tourney then each persons minimum bounty is worth starting stack, but you can only get half of this in a progressive KO. However, it's not as easy as just adding extra chips and working out your odds
at that point. If you have to risk a large portion of your stack to win a bounty then you will effect your ability to win bounties in the future, so your own stack size is important even if it isn't risked in the hand. You don't want to change your play too much because of bounties when you are risking almost your whole stack. So, to give an example, if the blinds were 100/200 and someone went in for 10 BB on the button and it folds to you on the big blind with 30K chips, you want to call with any two for a min bounty, but if the blinds were 100/200 and someone went all in for 10 BB on the button and you have 2500 chips then a closer to normal calling range is better.
As well as this, there are many other things which you need to adapt to when playing with bounties. You need to realise that if someone goes all in with a bounty, there is most likely going to be a lot of action, so when you shove, you need to adapt your range to include more hands which do better when called. For instance, a hand like 98s or 22 becomes less valueable when you shove with a bounty because when called, you are almost always flipping or behind, whereas a hand like A9 becomes more valueable because if people are going to call you with broadways and hands like A2-A8 then you are going to be in a better situation to double up. You also need to think about bounties when you are considering postflop decisions. You want to try to build the pot more often if your opponent has a bounty, and you need to remember that a bounty aware opponent will probably realise that you will bet more often.
So yeah, that's about it. I do find them very fun and interesting, and I do think that the bounty idea is a good one. I hope that advice makes sense
