I understand why the use of Huobi is prohibited in Nigeria. source

see same thing here every day, miner shows that i found "block" and i can see it in my found blocks at left side of screen, but it does not have blue "solo" pic and i'll receive just a few % of that block just like if i'm mining normal way. So, you are not alone.

It's my first time hearing about notco.in and 6,980,574 total players seems to be an exaggeration, as the famous platforms do not have a database with the number of players like this. mining it is considered a waste of time, especially since everyone can participate.
