Watching ads doesnt consume much data , but the problem very low pay , I mean 50 satoshis everyday is not even decent cents , thats the reason I stopped earning from okex.I know the task is easy but watching ads uses up alot of data bundles. So if you are buying limited data bundles like I do, you will be using up more money than you earn. So such faucets don't work for me, they would if I had unlimited data bundles.
