MADRID, SPAIN – Álvaro Romillo, the Spanish crypto influencer known as “CryptoSpain,” remains under provisional detention as investigations continue into a sprawling €250 million investment fraud and cryptocurrency scam. Romillo, alleged mastermind behind the now-defunct Madeira Invest Club (MIC), is facing serious charges of fraud, money laundering, and membership in a criminal organization, with the National Court of Spain spearheading the probe.
The Charges Against Álvaro Romillo
Álvaro Romillo Castillo stands accused of orchestrating a classic Ponzi scheme through the Madeira Invest Club. Launched in early 2023, MIC promised investors exorbitant, guaranteed annual returns, often advertised between 20% and a staggering 320%. Romillo allegedly lured thousands with claims of investing in luxury assets – from high-end vehicles and yachts to rare whiskey, gold, and digital artwork – all with guaranteed profits and buyback options. However, authorities assert that no legitimate business activity underpinned these promises. Instead, early investors were paid with funds from new entrants, while Romillo allegedly diverted substantial sums for personal luxury acquisitions. The scheme operated until its abrupt closure in September 2024.
Scale of the Crime
The financial fallout from the MIC scheme is estimated to exceed €250 million, with some reports pushing figures as high as €300 million. Initially, case materials suggested over 3,000 investors were impacted, though Judge José Luis Calama of the National Court has officially recognized 464 victims to date, grouped into four legal categories. These victims include private individuals who invested millions, alongside representatives from major companies, including an executive from an Ibex-listed firm. The reach of the scam extends beyond Spain, affecting individuals across Europe and Latin America, with some estimates suggesting the total number of affected individuals could be as high as 27,000 to 30,000.
Who Is Álvaro Romillo?
Álvaro Romillo Castillo, a Spanish national, cultivated an image as a cryptocurrency expert and tax evasion specialist under the online aliases “CryptoSpain” and “Luis Crypto.” He presented the Madeira Invest Club as an exclusive private investment group. His public persona and claims of financial acumen were central to attracting investors to what authorities now describe as a sophisticated fraudulent enterprise.
Investigation Details
The investigation, dubbed “Operation PONEI,” is being led by the Civil Guard’s Central Operational Unit (UCO) under the oversight of the Spanish National Court and Judge José Luis Calama. The fraud began to unravel in October 2024, following three formal complaints against MIC. However, a crucial red flag had been raised much earlier, in May 2023, when the Spanish National Securities Market Commission (CNMV) issued a public warning that Madeira Invest Club lacked authorization to operate as a collective investment institution.
The probe revealed an extensive international network, with Romillo allegedly controlling 52 shell companies and 106 bank accounts across at least 15 countries, including Portugal, the UK, Estonia, the Dominican Republic, and Singapore. A pivotal moment in the investigation was the discovery of a Singapore bank account holding €29 million linked to Romillo, which significantly contributed to his arrest on November 6, 2025. Following his court appearance on November 7, 2025, Romillo was denied bail due to flight risk concerns and remains in provisional prison. Authorities have since seized a trove of luxury assets, including 27 high-end vehicles, multiple properties, cryptocurrency wallets, and several yachts.
“The sheer scale and international reach of the Madeira Invest Club scheme highlight the evolving challenges in combating sophisticated financial fraud in the digital age. This case serves as a stark reminder of the need for extreme vigilance when confronted with promises of unrealistic returns.”
What Happens Next
Álvaro Romillo remains detained without bail, facing charges that carry potential prison sentences ranging from 9 to 18 years if convicted, depending on the classification of the fraud as a mass offense. As of Thursday, April 30, 2026, the investigation is ongoing, and a trial date has not yet been set. Authorities continue to trace and freeze assets linked to Romillo and the MIC scheme, aiming to recover funds for the thousands of victims. Romillo has also admitted to a separate, unreported €100,000 cash donation to the 2024 European Parliament election campaign of far-right MEP Luis “Alvise” Pérez, a matter under separate investigation regarding campaign financing irregularities.
Protecting Yourself from Investment Fraud
The Álvaro Romillo case underscores critical red flags that potential investors should always heed. Unrealistic promises of high, guaranteed returns, especially those exceeding market averages, are a hallmark of Ponzi schemes. A lack of regulatory authorization, as publicly warned by the CNMV in MIC’s case, is a definitive warning sign. Be wary of schemes promoted by influencers, particularly in the volatile cryptocurrency space, without verifiable credentials or regulatory oversight. Always scrutinize vague investment strategies and be suspicious of any pressure to invest quickly or in cash without proper documentation.
