I used to take part in bounty companies that lasted quite a long time and I can say that they paid quite well, not less than those companies that lasted only a month or two. Now I participate in the bounty of the company which managed to go for the last two weeks. I am attracted to this project because:
1)First ICO launched by a biotech company with a project related to AIDS research, and 2)INNBC Tokens will be spendable to buy classic iconic JDM cars from our INNBC JDM ONLINE GARAGE launched shortly after the ICO, so INNBC Tokens are backed by the value of JDM cars.

The thing about bounties is that the more people that are in the bounty then the more that they have to split it to get to everyone who participated so when the bounty goes on for long, it gives more time for more people to join which at the end means that there is more people sharing the bounty pool

I total agree with you, I don't like joining bounty that take a long time, if a bounty take a longer, the reward reduces because the longer the bounty waits, the more people join and the less the reward reduce, so the bounty I normal join these days, max is 8 weeks.

Usually when the duration of the pool continues to be the same or increase, but not much. Therefore, I come out of such projects.

it depends on the project we are talking about. In my opinion, a longer bounty doesn't necessary means lower earnings.

And it also depends if the bounty you're talking about uses the stakes system or a fixed price in tokens based in usd value for your work (better in my opinion).

If I can give you guys my opinion, I discovered an exciting one, which I just joined the bounty campaign: RAWG.

If you want to have a look and get some information, the ICO will start in a short period.

The ICO site is this one: RAWG. It's a video game discovery platform that converts your skills into goods and services.

You can earn tokens by playing your favorite games. The site is already working, with more than 50,000 games in the database and new games are getting added every day. This is the site: https://rawg.io/

Quite good looking, don't you think?

They have just started a very rich Bounty program for everyone who is willing to participate:

Another good thing, in my opinion, is that they pay you for your work a fixed value in tokens (with the value shown in USD) and they don’t use the stake system, so you will always know from the beginning how much you are going to earn for every task. And so you don't have problems related to the fact that: "more people are joining the less I will earn".

Have a look. I hope this information is helpful!

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.

In this matter, everything is well described by the mathematical term Coefficient of Useful Action. The longer the bounty, the correspondingly less reward per unit time. In a subscription company, the lower the rank, the more significant this gap will be. But in any case, the decision is yours.

If the project is successful, then you will earn a certain number of tokens, no matter if you participated 1 month or more.  If you have already undertaken this, then go to the end.  You will receive one of these things anyway.

This is not always so. But there is some truth in your words. I've been there too, a few coins that are worth nothing, and the work was done thoroughly. I lost time.
