Guinea’s central bank has warned that crypto investment platforms including LKY, also known as LuckyCoin, are operating as Ponzi schemes after users reported they could no longer withdraw funds despite visible account balances. The warning came as another platform, McGivern, was reported to have shut down on August 10, leaving users without access to their money.

According to the reported warning, hundreds of Guineans were affected by the platforms. Losses were described as ranging from a few hundred to several thousand euros, though no aggregate total was disclosed. One investor said they had put in more than 10 million Guinean francs, or about 1,000 euros, and was later asked to pay $1,000 in verification fees to recover the funds.

The central bank said the platforms fit a Ponzi-style model in which earlier users are paid with deposits from newer ones. It also asked mobile money providers to block accounts connected to the alleged scams, pointing to concern not only about the platforms themselves but also about the payment rails used to move funds.

McGivern was reported to have ceased operating on August 10, cutting users off from their accounts. The report also said Guinea’s judiciary is now involved in identifying those responsible and helping victims, suggesting the matter has moved beyond a regulatory warning into a potential legal and enforcement case.

Details on the operators behind LKY and McGivern, the size of total losses, and how much money could still be recoverable were not disclosed. The report also did not specify whether any formal charges or arrests had been made.

Why It Matters

The case matters less for global crypto markets than for local market structure and consumer protection. It shows how fraud tied to crypto branding can spread through informal investment networks and mobile payment channels rather than regulated trading venues, complicating oversight and recovery.

It also underscores the role central banks and payment providers can play when suspected schemes operate at the edge of the formal financial system. In markets where retail users may rely heavily on mobile payments, account blocking and judicial coordination can become the main tools for limiting further harm once withdrawals stop.
