Richmond Berks? Is it another ponzi or a legit oppt?

[SGM]

This is not an accusation topic, rather need for more information and opinions.

They claim to be buying and selling real estate with the money you invest, and then share the profits with all the investors (you get 1.5% of your investment daily).
They accept BTC and pay out in BTC as well. I tried them with small amounts of money, and it does work and they pay out as promised.

The question is, how long would it work?
They say "lifetime" of course. If it's some ponzi scam, then they won't have any real estate business, and they might just "crash" their server anytime and poof with the money.

They have a referral system, of course. I think you can't join without an upline name/code.

Their staff members page is quite odd, some people are fakes (linked to fake FB profiles) and some people seem real. Go figure.
There are several review sites out there who say that "Richmond Berks is a scam, better try my system which is 100% proven and solid" yada yada...
But they don't really prove or disprove anything, they are just clickbaits.

Generally it does seem legit and works coherently so far, but some things just don't add up (like their About page), and the company itself is lacking transparency IMO.

Any thoughts?
