I remember this fake mining browser from back then. I think 4 - 5 years back when there were shills allover different platforms trying to advertise it and convincing people that it was actually paying. Little did I know that it was still existing.
Unfortunately, newbies who don't know the requirements for actual Bitcoin mining still for such.
Anything that sounds easy to earn would
no doubt pull in users like moths to a flame, somemore with it being a web browser.
Based on the recent reviews, they seem to be allowing first withdrawals and banning/ prohibiting the subsequent ones.
