I would like to know if there will be a limit on the number of participants in each pool of the Bounty campaign?
Not yet for now, if we think it's enough we have to right to limit it.. so everybody who participate gets definitely a good amount of token
but you are interested to have more participants. Bountyhunters are interested in more coins. and sales of coins do not always depend on the number of participants. It is paradox
But it seems to me that still the Bounty campaign helps to spread the information about the project if the content is of high quality. Moderators should follow this quality to get a good result.
You're right. The quality of the content determines the effectiveness of the bounty.
