Spanish High Court Issues Arrest Order in Major 'Cryptospain' Scheme: €300M Defrauded

A significant development in the European crypto fraud landscape emerged when a Spanish High Court official issued a provisional custody order against cryptocurrency entrepreneur Álvaro Romillo Castillo, the figure behind the ‘Cryptospain’ brand, on suspicion of masterminding one of the continent’s largest investment frauds.

The case centers on Madeira Invest Club (MIC), an investment platform allegedly designed to deceive thousands of participants. Court documents reveal that the scheme promised returns of 20% annually through supposed investments in high-end assets. Rather than executing legitimate transactions, investigators allege that Romillo diverted investor capital for personal enrichment.

The Scale of the Operation

With a fraud value exceeding $300 million, this case ranks among Europe’s most substantial cryptocurrency-related financial crimes. The magnitude prompted Spanish authorities to prioritize the investigation and accelerate legal proceedings against the primary suspect.

Evasion Concerns Trigger Swift Action

The court’s decision to order provisional custody was substantially influenced by evidence of significant capital flight. Investigators documented approximately €29 million in recent international fund transfers, raising substantial flight risk concerns. These suspicious transactions suggested an attempt to relocate assets beyond Spanish jurisdiction, compelling the judge to act decisively.

Charges and Criminal Allegations

Beyond fraud, Romillo faces multiple serious charges including membership in an organized criminal enterprise and money laundering. The breadth of charges indicates prosecutors view this as a sophisticated, coordinated operation rather than isolated criminal activity.

Romillo’s arrest on November 6 marked a turning point in the investigation, with authorities working to locate additional proceeds and potential accomplices within the scheme’s network.
