MDX500 (www.mdx500.com) was just down for a while and displayed error message 522. It will not be a surprise if the scam goes offline. They all do aftleverer a few months. However, the boiler rooms and payment processors behind the scams are here to stay. In the case of MDX500, these are the boiler rooms that also run Blackstone500, for example. The Estonian BlueData OÜ operated the scam. Client-victims informed us that withdrawals and tradings had been stopped. Goodbye, money then! Another Estonian scam ripped off investors with Estonian regulators and law enforcement doing nothing.
