My friend has earned $20 000 in a bounty of company Titanium, but he has decided not to sell coins, then the project was cracked, and now it is $5 000 
$5 000 for a bounty is still a very nice amount! And yes, I believe if you join good campaigns you can earn $1,5k + on a project with signiture campaign included and Jr. rank.
Question for those complaining about low payment amounts, how much work and time did you invest in those projects and did you do only 1 campaign at the time? Yes I know, signiture campaign can be done only 1 at the time, but for the other campaigns there is no limitations.
Does anyone make an approximate calculation before joining a campaign?
