Spanish police have arrested the leader of the Madeira Invest Club, known by the alias "CryptoSpain," for allegedly running a Ponzi scheme valued at approximately €260 million. Since 2023, the scheme attracted over 3,000 victims by promising "guaranteed returns" through contracts involving cryptocurrencies, real estate, gold, and luxury goods. Investigations revealed that the organization conducted no actual investment activities, instead using new funds to pay returns to earlier investors, characteristic of a Ponzi scheme.
