Zondacrypto’s missing founder is still the only reported holder of a 4,500 BTC key, and his successor has now disappeared too
Polish crypto exchange Zondacrypto, formerly BitBay, is facing a deepening crisis tied to the 2022 disappearance of founder Sylwester Suszek and the later disappearance of his successor, lawyer Przemyslaw Kral. According to the report, Suszek vanished after sending desperate messages to family members asking for Bitcoin to secure his release, and his relatives believe he was killed. Prosecutors later linked one of his business associates, Marian Wszolek, to the case, though he also disappeared after charges were announced. The exchange later rebranded and operated through BB Trade Estonia, but scrutiny grew as Estonia tightened oversight of crypto companies. A report from the country’s Financial Intelligence Unit said nearly three-quarters of supervised firms had not filed a single suspicious transaction report in 2021, and Zondacrypto was described as one of them. Auditors in 2023 and 2024 also questioned whether the parent company’s reported assets were real. Kral, who took over after Suszek vanished, publicly claimed on April 16 that the company held more than $330 million in Bitcoin reserves, but said access depended on a private key known only to Suszek. The wallet he referred to, holding 4,500 BTC, had reportedly shown no activity for nearly a decade. Polish prosecutors now estimate potential losses of at least 350 million zloty, with more than 30,000 customers reported as victims, and the exchange case has been merged with the Suszek disappearance investigation.
