For the bounty campaign, I think most of them distribute tokens, and you can check it on https://bitcointalk.org/index.php?board=238.0 .

if you are looking for payment using BTC, ETH, and USD you can find it here https://bitcointalk.org/index.php?board=84.0 and https://bitcointalk.org/index.php?board=85.0

of course you also have to find out about the project you are going to follow about its potential so that you get a lot of benefits.
