It mainly depends on what the campaign is. If there is a decent campaign with a large amount of participants then you are correct, the earnings will be much lower than normal.

The duration of the campaign would not tell how much a participant is going to earn, only the stakes rewarded to them. The duration is not concerned with the profit that we could earn and IMO, we should be more concern if the project is going to succeed or not. Definitely, the succession of the project somehow ensures that there are investors and that the coin will certainly be listed on the exchanges therefore the token/coin is possible for high-profit trading. I have joined previous campaign that took months before it ended but it did not succeed, the reward was given but we can't even gain something from it. We were expecting this token to be sold at higher prices but we end up just hoping.

Indeed. I experience this issue. The more participants the lesser reward you recieve. And staying at the camapaigns for so long getting a less paymetnt because of too many participants.

More like the probability of getting your tokens will get lesser and lesser, there is no reason for any project to reserve their tokens that long if its really fair or non fishy. I seen some project keeping it for lots of reason, not finalized, waiting for the right timing so their coins could flip, or simply doesnt want to give you. Thats the harsh fact when things are not really regulated

the longer the bounty runs the fewer the token you will earn after the ICO,why?

becuase the allocated budget will be divide to the number of participants the longer the bounty the more participants participate in the bounty.

Is not the case, it would depend on the number of participants and level, if there are too many people involved in the bounty, earnings would be very few, if your level is the legendary hero, then you will have a lot of bounty.

Yes, your friend is right. If the bounty campaign goes too long, then there are too many participants and you will get very little.

It might depend on the percentage of the bounty allocation that is being put into the signature campaign. At some times when the bounty managers realize that the campaign might run for longer than expected, they tend to reduce the weekly stakes so the bounty allocation can last until the end of the bounty campaign. You are right though, the shorter the bounty period the more stakes you get.

Your point of view has some truth. When the duration of a bounty campaign is extended, and the total amount of bounty does not increase, your weekly income is decreasing.

The ICO project initially allocated a certain amount or percentage of the collected funds. You won't get any more. You lose your time in this case, because you could easily take part in the companies of other ICO projects.
