Zondacrypto, once a leading cryptocurrency platform in Eastern and Central Europe, has vanished after both its top managers went missing, leaving hundreds of thousands of users locked out of their funds.
This incident serves as a reminder to the crypto industry, which is still fighting for recognition, of how quickly people's trust can disappear when they don't know what is happening with their investments.
The damage is not limited to Poland and Estonia, where this cryptocurrency exchange originated. Cryptocurrencies have gained political and institutional recognition partly due to former President Trump, whose family's cryptocurrency venture reportedly earned $1.4 billion according to The New York Times.
Nevertheless, Zondacrypto demonstrates that the old problem of fraud in this business remains relevant. The ZND token has lost 99.9% of its value, and the platform holding client deposits has been inaccessible since April.
Two Bosses Have Vanished in Four Years
The BitBay platform began operations in 2014 in Katowice. Its founder was Sylwester Suszek, the son of a miner, whom Polish media and Cryptopolitan called the 'Crypto King'. According to earlier reports, he disappeared in March 2022 at the age of 34 after going to a fuel storage facility near Katowice for a meeting with his associate Marian Wszołek.
His family believes he was kidnapped and murdered. Later, Polish prosecutors charged Wszołek with membership in an organized crime group, large-scale VAT fraud, money laundering, and illegal deprivation of liberty in connection with Suszek's disappearance.
The lawyer representing Suszek's interests, Przemysław Kral, has now taken control of the case. His last message was posted on social media on April 16, 2026, urging all his clients to remain calm. Four months have passed since then, although the Times claimed he was seen several times in places like Israel, Botswana, and Dubai.
Robert Nogacki, a Warsaw-based lawyer representing clients who have lost access to their assets, stated the following:
"It was a scam from the very first day."
The Wallet That Only the Missing Man Could Open
Kral assured concerned clients that Zondacrypto held 4,500 Bitcoin, worth about $336 million at the time, and that only Suszek had the keys to them.
However, according to Recoveris, a company specializing in blockchain analysis, this is not true. Their investigation into Zondacrypto revealed that Bitcoin reserves lost 99.7% of their value: from a recorded peak monthly average of 55.7 $BTC in August 2024 to 0.18 $BTC in March 2026. As of April 1, Zondacrypto had only 0.086 $BTC left, equivalent to approximately $9,700 USD.
According to Recoveris, similar European exchanges held an average of 308 $BTC in their main hot wallets. Recoveris noted that between mid-December 2025 and early April, the company initiated 511 transactions from Zondacrypto wallets to a deposit address at Kraken, totaling about $21 million.
The exchange refused to disclose wallet addresses as proof of cold reserves, citing the EU's MiCA and DORA regulations. Both regulations do not prohibit the disclosure of this information.
Estonia Revokes License, Brussels Deadline Expires
On June 29, 2026, Estonia's Financial Intelligence Unit (FIU) revoked the license of the company BB Trade Estonia OÜ, the parent company of Zondacrypto. Previously, on May 18, the FIU had already temporarily suspended some of the company's licenses, preventing it from accepting new clients.
The agency added that its powers are limited, as its goal is to monitor compliance with anti-money laundering laws, not to verify whether client funds actually exist and are stored securely.
The timing of the crash added drama to the situation. Article 143 of MiCA stipulates that service providers operating under previously applicable national regimes can only continue their activities until July 1, 2026, or until their application is approved or rejected by the European Securities and Markets Authority (ESMA). Zondacrypto's Estonian license disappeared just two days before this deadline.
Prosecutors Include the Case in Organized Crime Scheme
According to a statement published on August 3, the investigation into the 'Zondacrypto' case, being conducted by the Regional Prosecutor's Office in Katowice, has been merged with an investigation being conducted by the National Prosecutor's Office of the Silesian region under its Department for Organized Crime and Corruption.
The prosecution is conducting a series of investigations concerning the creation and operation of BitBay and Zondacrypto, including an investigation related to the disappearance of Suszek.
Polish Prime Minister Donald Tusk accused Zondacrypto of having ties to Russian criminal syndicates and intelligence services, pointing to the company's financial links to right-wing politicians and events in Poland.
Speaking in the Sejm on April 17, he stated that Zondacrypto's rise to success began "with money from the Russian mafia."
For now, clients are concerned with just two questions: the fate of their deposits and the future of the two missing executives.
