Mining City's Crypto Scam Keeps Evolving—And That's the Problem
Gregory Rogowski is still running Mining City, an unregistered securities scheme that keeps changing its pitch but never changes its core con.
BehindMLM first exposed Mining City a year ago. The operation hasn't cleaned house—it's doubled down. Rogowski, also known as Grzegorz Rogowski and "Greg Strong," continues operating what appears to be a Poland-based fraud with no legitimate corporate address listed anywhere online. Not on the website. Not on social media. Nowhere.
The most recent shift tells you everything: Mining City stopped pretending it had products. There are none. Affiliates can't sell anything except the chance to become an affiliate themselves. That's the whole operation.
Instead of peddling mining equipment or software, Rogowski now dangles returns in bitcoin and something called "bitcoin vault"—payments stretched across 1,100 days to make the money feel less imaginary. The entry price points start small at $300 but climb steeply: $600, $1,200, $2,400, $4,200, and $12,600. All payments go in bitcoin or bitcoin vault.
The compensation structure is where the machinery of fraud becomes clear. There are eight affiliate ranks, each requiring recruits to dump thousands more into the system. A "City Builder" needs at least five recruits paying $600 each. A "City Developer" needs a City Builder in three separate downline legs. Climb higher and the requirements spiral: City Managers need three City Developers. City Chief Managers need three City Managers. The pyramid keeps building until you reach "Governor"—someone who's somehow supposed to generate $100 million in downline investment volume.
This is textbook multi-level marketing wrapped in crypto language. The money flows up. The people at the bottom lose.
What makes this particularly galling is the evolution. Mining City isn't sitting still—it's adapting to stay one step ahead of regulation. The shift to bitcoin and bitcoin vault means transactions leave fewer paper trails. The 1,100-day payout window buys time for money to move through the system before victims realize they're not getting their promised returns. By changing the compensation plan, Rogowski creates cover for existing members to recruit others under new terms.
Rogowski's LinkedIn shows Warsaw as his location. That's probably where the servers are, where the marketing happens, where he watches money flow in from desperate investors worldwide.
None of this is accidental. This is a man running an unregistered securities investment scheme—illegal in virtually every jurisdiction that has crypto regulations. He's not offering shares in a legitimate mining operation. He's not managing actual cryptocurrency assets. He's collecting bitcoin from new recruits and redistributing scraps to old ones, calling it returns.
The fact that Mining City updated its compensation plan means fresh victims arrived. The scheme worked well enough to expand. Until regulators actually shut it down—which hasn't happened yet—Rogowski will keep taking payments and calling it business.
