Most campaigns will pay based on stakes, which are a share of the total pool of allocated tokens for the campaign (/concept). At the end of the campaign, stakes are normally calculated by adding all the awarded stakes and calculating their token equivalent as a ratio to the campaign token pool. Therefore, the more people that participate, the less amount of tokens you will receive (many do not even put a limit to the amount of participants). Additionally, since the campaign pool tends to be a fixed amount, the longer the campaign, the less tokens you will get for your shares.

Not all campaigns function by the above criteria. BTC based campaigns for example tend to pay a fixed amount per post, establishing an upper limit to the amount of posts that are considered in the payment procedure. These campaigns tend to delimit the number (and quality) of participants according to budget and other factors.
