Even paid to click sites set the minimum withdrawals at $1. And THEY have a hard time to maintain newcomers who realize you need to click 200 ads or watch 50 videos just to get that minimum.
Way too high to keep those people who try it out to get interested. Unless you are able to pay big amounts per action.
I tried those and 1$ still huge for the clicks and ads watch it makes me get bored and stay away to the platform before, also I get surprised for reading a $50 limits? for sure people will not spend their money since most provably that they will not get their compensation for their efforts since anytime the owner might shut their site if he cannot get a good result and efforts will be wasted for that scenario.
