This is a reality! Most of people join bounty and these people are uneducated from 3rd world countries. I don't want to be rude, but it is true, because in Europe and America people gain much more on usual job and twitting and posting in social network for some bucks isn't for them.
That sadly the truth, not because that 3rd world people can't get more money from their main job, but because while for Europe and America, they only waste that bounty money for shitty fake social activity or starbuck, in 3rd world country the money from bounty can be used to pay for education, food and event rent.
