So wake up and smell the roses: There is no trading going on. Your deposits pay the profits for earlier investors and new depositors pay your profits. Just like any other Ponzi / HYIP scheme.
OK, if we assume that is a ponzi it's a miracle that is still standing, since many investors entered near the btc top price or close (nov 2013 - apr 2014), and they got their investment automatically converted in USD at the price of the time that they invested and got paid interests on
that capital since then. And from some time many are getting the option to withdraw their capital beyond the interests already paid.
So unless the user base grown exponentially in the meanwhile a ponzi like this should be a short-lived fail, which is not even very anonymous given that they are operating through several pay processors and are effecting bank wires (which in itself is not a guarantee on the return
of the investment, of course, but is already some steps ahead of pirate-likes).
It's not a miracle the ponzi is still standing. They pay less interest to begin with than one of the ponzi's I am in that is older than bitcoin-trader.
