I have checked the latest active bounties on bountylord.com and found many of them but only few are rated as 3 or 4 so any of you here working for any of those bounties listed there and found it trusted source of earning stakes/tokens/coins... I want to do the twitter campaign...
If you just want to join in twitter campaign i don't think you need to do research before you join. Just join if you think that project is good and don't forget to read everything about the rules.
