I want know if these BTC generators websites are really working? I have tried using one and made few BTCs, and when I was about to receive them, I was told that I should pay a certain amount of BTCs before the BTCs I generated can be sent in my account. So I don't want to send and never receive, and I want to be sure if they are working or not. Has anyone used that?
No they aren't really working, there's no way to generate bitcoin with such software that hasn't inline with pools. And it was just a deceitful move by those developers of that bitcoin generator that you had encountered. Don't be fooled by them, just forget those fake generators and they won't really make your btc's double.
