Wallets tied to defendants in Spain’s Arbistar case recorded more than 20,000 BTC in combined inflows and outflows, about $1.1 billion at the time, in the three months after the platform froze investor accounts, according to a Guardia Civil investigation reported by Bitcoin.com. The figure reflects gross transaction volume, not confirmed losses, as the same coins can move between addresses multiple times.
Spanish investigators have uncovered extensive Bitcoin movements linked to the Arbistar Ponzi Scheme, including transactions recorded after the cryptocurrency investment platform collapsed in September 2020.
According to reporting published by Bitcoin.com on October 26, 2026, a Guardia Civil investigation identified substantial transfers involving wallets associated with the platform’s defendants, raising further questions about the destination of funds entrusted to the company by investors.
The latest findings concern transactions made around the platform’s collapse and in the months that followed. Between January and March 2021, wallets attributed to individuals facing prosecution recorded inflows and outflows exceeding 20,000 BTC.
The combined value of those movements was reported at more than $1.1 billion, based on Bitcoin’s price at the time.
Arbistar operated through Arbicorp in southern Tenerife, Spain. The platform attracted customers by promoting automated cryptocurrency trading and unusually high returns.
When accounts were frozen in September 2020, investors were left unable to access their funds, prompting investigations into the business model and the handling of customer deposits.
The Arbistar Ponzi Scheme case has since developed into a complex legal and financial investigation involving alleged fraud, suspected money laundering and efforts to establish where investors’ assets went.
According to the findings reported by Bitcoin.com, the movement of cryptocurrency did not stop when Arbistar suspended investor access. Investigators identified significant transactions involving wallets attributed to defendants during the first quarter of 2021.
The reported transfers exceeded 20,000 BTC in aggregate. Their estimated value was approximately $1.1 billion at the time, although the precise dollar equivalent depends on the valuation date and Bitcoin’s market price.
An important distinction for crypto investors is that transaction volume does not necessarily equal the amount stolen, the value still missing or the total balance controlled by a particular individual.
The same Bitcoin can move between several addresses, creating multiple recorded transactions without representing an equivalent amount of new money.
Investigators are examining the relationships between the wallets, the people allegedly connected to them and the circumstances surrounding the transfers.
These questions are central to determining whether the movements had a legitimate explanation or were part of efforts to obscure the ownership and origin of assets.
The Arbistar Ponzi Scheme investigation also highlights the limitations of interpreting blockchain data without additional evidence. Bitcoin transactions are publicly recorded, but wallet addresses do not automatically reveal the identities of their controllers.
Establishing ownership and criminal responsibility requires investigators to connect on-chain activity with other financial, digital and legal evidence.
The original collapse affected an estimated 32,000 investors across Spain and several international jurisdictions. The platform reportedly promoted weekly returns of approximately 28% through automated cryptocurrency trading, a promise that helped attract substantial customer deposits.
When the company froze accounts in September 2020, it attributed the disruption to a problem with its automated trading bots. Investors subsequently faced uncertainty over their balances, while authorities began examining the business and the flow of customer funds.
Investigators also identified a transfer of approximately 881 BTC to external wallets on the day of the collapse.
According to the reporting, these coins were worth around €32.5 million several months later. Their subsequent market value does not, by itself, establish whether the funds were sold, recovered or remain accessible.
The legal proceedings have focused on allegations including aggravated fraud, falsification of documents and participation in a criminal organisation. Arbistar founder Santiago Fuentes Jover and associate Diego Fernández Nojarova have faced prosecution in connection with the case.
Bitcoin.com reported that Spain’s Audiencia Nacional imposed prison sentences of 16 years on Fuentes Jover and 11 years on Fernández Nojarova following appellate proceedings.
Separate questions surrounding cryptocurrency transfers and possible money laundering remain under investigation.
The case offers several lessons for people considering investments in digital assets. First, advertised returns should be assessed against realistic market conditions.
A promise of consistent weekly gains at exceptionally high rates deserves careful scrutiny, particularly when a company does not provide independently verifiable evidence of its trading performance.
Investors should investigate the people and legal entities behind a platform before depositing funds. Transparent ownership information, independently audited financial statements, clear withdrawal terms and appropriate regulatory standing can help investors evaluate the risks, although none guarantees that an investment is safe.
Blockchain transparency should not be confused with automatic recovery. Although Bitcoin transactions can be examined on public ledgers, tracing cryptocurrency does not necessarily reveal the ultimate owner of a wallet or give victims immediate access to its contents.
Recovery may require court orders, cooperation between jurisdictions and the identification of assets that can legally be seized.
The Arbistar Ponzi Scheme proceedings also demonstrate why investors should distinguish between allegations, court findings and confirmed financial recoveries.
Large transaction figures can indicate the scale of an investigation, but they do not independently establish the total losses or prove that every transfer was criminal.
The central question remains whether authorities can identify and recover assets that may be available to compensate victims.
As investigators continue examining the transaction trail, the Arbistar Ponzi Scheme remains a reminder that identifying cryptocurrency movements is only one stage of a much longer process.
Determining ownership, establishing liability and returning money to victims are separate challenges, and the reported transfers alone do not resolve them.
