I joined Picoworkers a long time ago because I heard that it was easy to make money, well I did find it was easy to make money as I did not need any skill and I could start working right away and make money on my first day. But the sad thing is, you cannot make decent amount. Now, Picoworker rebranded to Sproutgigs and allows users to sell their gigs just like Fiverr. You create a gig and when someone buys it, you make money. I joined Fiverr a long time ago but apart from a couple of gigs, I have not sold much on Fiverr.
