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...
It's very hard to know. Personally, I would prefer not to entrust some projects, namely bounty managers. You can follow him from project to project and get your profits.
