Thank you for your reply. There are many scam site making people fool. I want to know is there any site where I can start mining for free?

Dear Concern,

I am beginner in bitcoin mining sector. I have started mining in btcminer.services. After reaching minimum withdrawal amount I withdrawn but it showing that without premium membership I can't withdraw the coins. I want to mention here that I have started mining in 4 browser with same IP (home pc). Now What should I do to transact bitcoins? I have wallet in Coinbase. Thanks in advance.

Regards,
Al Raji
