Binance Client Data in Russia’s $700 Terror Case Puts Bitcoin (BTC) in Focus

Crypto News

Binance supplied Russian investigators with customer records that became the basis for a terrorism-financing charge against Yuri Belenkiy, a 49-year-old IT specialist accused of sending just over $700 in cryptocurrency to a Ukraine fundraiser. The case is being followed as a market-structure test for Bitcoin (BTC), the benchmark crypto asset, because it shows how law-enforcement requests can convert a centralized exchange’s know-your-customer files into criminal evidence. Documents show Belenkiy responded between January 2023 and March 2024 to online appeals from exiled Russian journalist Arkady Babchenko, who said donations would buy medical equipment for Ukrainian soldiers. The file includes Belenkiy’s phone number, address, passport scan and Bulgarian residence permit, together with two emails sent from an address Binance lists for Russian and Belarusian law-enforcement requests. Investigators said the transfers supported the Azov Brigade, a unit Russia has designated as terrorist; Belenkiy was detained in September 2025 and remains in custody awaiting trial. Binance has said it processes lawful requests under applicable legal, privacy and regulatory requirements. A spokesperson said the exchange does not write or enforce any jurisdiction’s laws, does not determine charges and does not decide how governments use information in legal proceedings. Chief executive Richard Teng wrote on X on Aug. 17 that Binance follows lawful, regulated procedures globally and cooperates with authorities even where it has no commercial presence, citing its practice of answering U.S. law-enforcement requests despite not operating there. The disclosure arrives after Binance’s 2023 guilty plea to U.S. federal charges, part of a $4.3 billion resolution with the Department of Justice covering anti-money-laundering, sanctions and money-transmitting violations. His transfers were donations to a Telegram-based fundraiser, not an airdrop, but moving the funds through a centralized exchange left a trail investigators could link to him. The episode also contrasts centralized account infrastructure with self-custody crypto wallets, where users, not platforms, hold the private keys.

The disclosure has revived questions about what Binance owed Russian authorities after announcing its exit from Russia in September 2023 and selling its local business to Commex. At the time, the exchange said full withdrawal could take up to a year as customers moved to the new platform. Mike Bystrov, founder of crypto-advisory firm Stellar Consulting, argues that because Belenkiy holds Bulgarian residency, his data may fall under the EU’s General Data Protection Regulation. Under GDPR, Russia is not recognized as providing adequate data protection, so transfers of personal data to Russian authorities require a specific legal mechanism or a narrow exception; Bystrov maintains Binance had no obligation to comply after leaving Russia and may have been prohibited from doing so. Binance challenged that reading, saying it reviews requests for compatibility with sanctions, legal, privacy and regulatory requirements. The exchange did not answer whether the transfer violated GDPR. The European Data Protection Board declined to comment, saying enforcement falls to national authorities, and Bulgaria’s data-protection commission did not respond to questions about the case. Belenkiy holds a Russian passport and a Bulgarian residence permit; whether he was registered with Binance as an EU customer has not been confirmed, and his lawyer did not answer questions. The documents do not specify whether the transfers involved Bitcoin, an altcoin, or another digital asset. The First Department, a human-rights group that said it obtained the documents from Belenkiy’s relatives, argued that EU residents would not expect an exchange that declared a Russian exit to keep communication channels open with the country’s investigative bodies. One investigator request also asked Binance to identify other customers who sent cryptocurrency to wallets promoted by Babchenko; the documents reviewed did not state whether Binance answered that request. Babchenko said it was inappropriate for an exchange to share Russian customers’ donation details with Russian law enforcement. Human-rights activists say dozens of Russians have faced prosecution over crypto donations to pro-Ukraine causes.

The legal core of the episode is the evidence chain set out in the Investigative Committee’s Oct. 13, 2025 statement and in the interim case summary sent to the Prosecutor General’s Office; both documents expressly list the Binance-provided transactions as the basis for the terrorism-financing charge. That makes this a compliance and privacy precedent rather than a price event for Bitcoin or any other token. It shows that customer records collected through know-your-customer checks can be requested by foreign law-enforcement bodies even after a company has formally withdrawn from a market. For users, the distinction between centralized custody and self-custody wallets, where the user alone controls the private keys, is becoming a legal question as much as a technical one.
