You will never know what they do until you've tried and try and try it again and you couldn't still get it. They will stretch it forth to you, you will see it but you may never get it, while they are generating huge on your service to them. Speaking from experience most so called online paying sites are online scamming sites. They use you to get what they want. You spent your money, your time, your energy and even your ideas but at the end, no pay.
I knew what I'm talking about because I've been there. They will tell you complete some task and get paid. But to your supprise after working for so long, you will get tired and dropped out but they get their own money and your own invested resources will be gone. At times they set a minimum withdrawal balance that you may never achieved and even if you get it, they tell you the page is now on "Err 409" can you imagine?
That's what i know they do and it's just exactly what they do, though its good to give it a trial incase, you are lucky to get the truthful ones in future. But try with care. Do more of steemit than online paying sites. Steemit is the best you work and you get paid, you know why and how you are paid. Steemit is not in their class that's why you need to work on and earn more and your impacts will also be felt in the world. STEEM ON!
