I have a friend who made 1.76$ with 2 referrals and around 1 week.

I'm one of his referral and I use CryptoTab for around 4h in that 1 week, I suppose his other people wasn't really active, they are in Cameroun with a cheap computer or none.

So maybe it works.

I mean they ask no cash, but they take a part, if they quit they lose their income (cryptotab), it would be stupid to do that.

The issue for me is that you mine bitcoin and you lose cash when you do it, you only make money when you have referrals because you make money on them, so they could mine another crypto, it would be better.

I'm going to test and come back with an answer.

Did you people was using the software or you have no idea?
