Arbistar-Linked Wallets Moved Bitcoin After Collapse, Report Says

Spanish investigators traced substantial bitcoin movements through wallets linked to defendants in the Arbistar cryptocurrency fraud case after the platform collapsed, according to reporting on Guardia Civil findings. The transfers form part of a separate investigation into possible money laundering connected to the failed investment operation.

Bitcoin.com News described the post-collapse movements as exceeding $1.1 billion. Spanish reporting carried by elDiario.es, citing a court order and investigators’ findings, put the transactions at more than 20,000 bitcoin between January and March 2021, worth approximately €710 million at the time.

Those figures describe money moving into and out of wallets, not a newly established amount stolen from investors. They should not be treated as a measure of recoverable assets or as proof that an equivalent sum remained under the defendants’ control after the transfers.

Arbistar, based in southern Tenerife, collapsed in September 2020. According to the Spanish reporting, investigators also identified a transfer of 881 bitcoin to other wallets around the collapse, with those coins reaching a value of €32.5 million several months later.

The platform’s business rested on claims that automated cryptocurrency trading could generate investment returns. Spain’s National High Court described the underlying operation in its annual reporting as a pyramid-style arrangement in which part of the money received from investors was used to pay earlier participants, encouraging further deposits and recruitment.

Investors transferred cryptocurrency to wallets controlled by Arbistar and lost direct control over those contributions, according to the court’s account. The arrangement offered participants the choice of withdrawing purported earnings or adding them to their investment, helping sustain confidence before withdrawal problems emerged in 2020.

The scale of the underlying fraud is distinct from the later wallet activity. A September 2025 announcement from Spain’s judiciary said the case involved €200 million and approximately 32,000 investors, illustrating why tracing the destination of funds remains important beyond the prosecution of the original scheme.

According to elDiario.es, investigators found that a cryptocurrency mixing service was used near the period when Arbistar began reporting liquidity problems. The report described the service as a means of obscuring the origin of funds and said investigators nevertheless identified some beneficiaries as relatives of the administrators.

The reporting also describes legal disputes over the scope of the money-laundering investigation and the inclusion of additional suspects. Those proceedings concern potential responsibility for moving or concealing funds; they do not establish that every person receiving cryptocurrency participated in the original investment fraud.

The investigation’s next task is to clarify who controlled the transfers, where the funds ultimately went and whether particular transactions constituted money laundering. The reported wallet movements provide leads for that inquiry, but the transaction totals alone do not establish how much can be returned to affected investors.
