You have such result, because you choose projects based on a high level of interest. There will be no other results. Pay attention to good projects with a lower level of interest, but with stable idea and working team. To focus on ICOBench, I do not advise you, as a result, you will get not very promising projects, together with a large number of people in campaign, and as a result, have as you said, $ 10 per week, which is not bad for a newbie, to be honest.
