Not always the case, the longer the bounty lasts, the less earnings. It all depends on the project, on the number of participants, on the volume of the pool allocated to the bounty, and on the honesty and integrity of managers.

By using some logic, yes, that's correct. The reason why you will get fewer earnings/bounty when bounty you joined become longer because there will be man participants joined on there and that will make you get fewer earnings. The only way to avoid it is join on campaign/bounty which has limited participants or joined on weekly payment.

The longer the bounty means low rewards. If a bounty continues more than 4 weeks, many participants join it each day. So, the cake is divided between too many people. Eating the cake with 100 people and eating it with 500 is different. The income decreases. There must bu limitation for the bounties.

The first and dominant reason is if the campaign reaches its hardcap or not, simply put that if the campaign is successful or no, it will increase the pool for the bounty hunters and will definitely let you earn more than you expect. The  umber of bounty hunters and the lengtg of bounty campaign are 2 different variables and usually does not affect that much unless you have got half of the bounty legendary people...

Gains from bounties generally depends on number of participants and not duration, unless if more people join at the end. The lesser the people, the more the profit or proceed.

I advise you to stay and work. You will not get anything when you leave the project. I believe that you need to go to the end.

Its a case to case basis I think it defends on the project some project even if they are long they still pay good. But some cases yes its true the longer the bounty the lower member will just get little. It will only benefits the high ranking bounty member.

If you have a low rank, then yes, with every week your possible income will decrease. But the converse is also true, if your rank is above the average among the participants in the bounty campaign , the amount of the payment will increase.

I also think that the longer the time the less bounty reward. and I don't like when companies are postponed.

There are many projects that, when extending the dates of the program, also increase the prize fund of this program. If the project does not do it then your profit will be less
