This company claims to be an online bitcoin cloud mining operation when in fact it's a facade for a scam! You simply input your BitCoin address and "earn" satoshis by the hour and if you pay to upgrade to a higher level, your satoshis/hr increase while also earning an affiliate bonus for spreading your affiliate link. Ultimately when you made a withdrawal into your BitCoin wallet, you may get one to three small withdrawals actually deposit and then nothing thereafter (just says pending). The company has a contact page with the following displayed: Company number: 09951039 Registered office address: 20-22 Wenlock Road, London, England, N1 7GU. An internet search of the above address will have details of other scammers using the address in the past. BUYER BEWARE: Don't PAY to upgrade!
