It depends on how you collect it because if you are wasting time collecting free Bitcoin, it should be useless in my point
It is right, there are a lot of people who still collecting free Bitcoin or claiming captcha like Raiblock, I think it can not enable you to earn a lot of money or even pay your electricity bill
Yeah but if there were not people like that, life would be more difficult when there are no one works for small jobs and small salaries
