There is no mention that they are doing mining at all, nor a figure for their current mining power, or blocks that they found, just some vague explanations that they are investing any deposits and promises of large gains. It actually looks like they are incorporated to a superficial check, the certificate of incorporation does lead to a gov.uk site that lists the company and other companies that I'm aware off.

So:

• No mining
• Large featuring of referral rewards
• Vague business plan
• No mention of the owners or team

I'd treat it as a scam until palpable evidence of the contrary is presented.

Don't expect to make easy money using HYIP(high risk yield products) similar to what you mentioned. Most of them are anonymous and cannot be traced to an actual individual which leads to the conclusion that they are scared/concerned about getting caught. They do not seem to have proof of running a mining operation aswell.

Stay safe.
