Now in social networks 1500-200 participants. You do not have a very big reward and I do not think that someone will want to advertise the project for two months for five dollars. Or it is necessary to increase generosity or make a limited number of participants
How do you know how many participants there are? Where do we access that information? Transparency in these type of bounty campaigns is important because if the number of participants is inflated then a participant can literally be paid nothing for several months of work and not have any proof that the numbers were fabricated.
