Might be? in my own experience these high ranking profiles are coming when a bounty campaign will soon be ending because they can get a lot of stakes doing that,those who worked hard for months will only be 1week for those high ranking profiles especially when we are talking about the signature campaign allocations its too unfair for those low ranking profiles like me.

If you don't waste a lot of time on it - it will be better to stay for you, because while a lot of people will earn some coins, you will earn max elementary, because of your start at the beginning. So, but the same time, you may earn as all another, if you will go out, but the same time find out something more expensive. Also, in case of delaying their campaign it means, that they can't reach the result! So may be your friend is right.

Somehow its true,if we are talking about signatures,it is unfair for those low rank profiles who worked for months and then suddenly bunch of high ranking profiles will come before the bounty ends,most commonly last week of the bounty and these hero/legendary accounts will come to get good amounts of stakes better than your 2months of work,1 week of hero/legendary accounts would be equal to jr.member or member accounts who worked for 2months,that is whow unfair it is.

Yes it is especially in the signature campaigns it wont give you much when there too many high ranking participants,you have worked for 2months and and these high ranks will only post for 2weeks and they will have more than stakes that you will get? isnt that unfair for the lower ranks? that is why i dont usually join campaigns which has a lot of high rank participants.

Yeah it could be like that,because one week of these high ranks will be equal to a month of work for these low ranks like me,and most of these high ranks are joining campaigns which are about to end so they could get stakes without having efforts.Unfair indeed to those people who are posting for months ,and i hope the bounty managers will see this problem sooner or later.

Now a large selection of bounty. I realized that it's better to look for bounty, which are paid with coins rather than stakes. Of course, there are not many such, but if you look, you can find it. Then you will know how much you will earn and there will be no misunderstandings. Or to look for good bounties, which attracted few people, but good rewards. I now participate in this and wear her signature 

Yes I think so. Because we usually get stakes. NOT money!
Fixed percent of Cap (100 tokens) - we can get it for 1 weeks or for 12 weeks.
Do you feel the difference?

Yeah, sometimes good projects somehow can't attract people to heir bounty program. Reason could be that their bounty thread is too plain, unprofessionally designed, maybe too complicated and bounty thread gets lost among 10s of other bounties which have more attractive title or name.
Or the project does not focus marketing on bitcointalk but on other channels and they collect huge amounts of money even tho the ANN thread looks unpopular. But the point is that they will distribute 2 or 3% of sold tokens to bounty participants and that can mean big amount per participant if there are not many of them.

Payout usually centers around rank not length. The higher your rank the higher the pay.

I think it also depends how they reward people whether through stakes or just a fixed amount. The point of a bounty is that people earn the rewards. You also have to look at the budget too. A good project that's planning a bounty also has an airdrop where you earn 15,000 tokens for downloading their app and providing feedback. https://algebraix.io/
