Bitgrow.biz is scam website. Do not invest money with them and you will lose it. Let me tell you my experience with bitgrow.biz
I had invested bitcoin value worth $60 with them . After login I can see my investment and earning. Requested my first payout after two days of investment and the same was processed as well.
From second payout request onward they are not processing the request any more. I contacted then via email but no response. From last few days the website is down. See below the details taken about Bitgrow Investments LTD from Companies House UK. I am not sure this is the same company but the company registration number given was same at bitgrow.biz website.
