As a full member, I received a total of 1300$ in my last campaig and it lasted for almost 3 months including the distribution of token.
Still 1300$ it's a good reward)) who receives over half 300 bucks, and someone was 7000 $. I can not say how much a month, sometimes a month $ 300, and sometimes a month comes to $ 3000, but this payment for projects that were 3-4 months...
Mostly in now like this. Every bounty last for few or several months. And if we calculate and divide then maybe its possible to get bigger amount, but for that i will have to say that only high ranking members can say that they have that amount. Dont think that members and below could do this with single campaign, dont say this is not possible but again very hard. However if some is participating in all bounties that one project can offer chances for that person to have 1000$ a month are bigger.
