Yes, most of the project campaigns are paying participants who join them. But the problem is whether the payment is in accordance with what they said before? It might just be a lot lower than what they were offering before. There are also projects that don't pay participants for certain reasons. You can check recently completed projects now, they are not paying participants for some reason. But such a thing is a no-brainer. Because it will make our enthusiasm decrease in doing work. Even so, disappointment will arise, because we have done the work according to their wishes, but in the end they ignore all the participants they promised before.
