I have made over $100 on picoworkers, therefore, I believe you can make money on the site, but the question is how long does it take to make money. You cannot do 100 tasks in a day. It is not possible due to the time constrains as well as the picoworker system.There are hundreds of tasks available in there. One task pays 3 cents. So, if we do the Maths, we can see that it is possible to make $3 there. 0.003 X 100= $3. However, it takes A LOTS of effort to complete those 100 tasks.
