Are these platforms that operate in only certain countries? I have not heard much about them outside of some people talking about them here but that could be due to where I am located.These sites are Rapidworkers, Microworkers, Picoworkers. All of them have 1 way of earning is Performing micro tasks. They are the best not only for 2021, but also from 2009 to the present time, they remain a relevant way to earn money and do not lose their popularity.
