Zonda Says $334M in Bitcoin Inaccessible After Founder Disappears

• Zonda exchange discloses inability to access 4,500 BTC cold wallet valued at $334 million amid withdrawal surge.
• Leadership transition failures and the founder’s disappearance underpin insolvency allegations and regulatory scrutiny in Poland.

On April 16, 2026 (UTC), Cointelegraph reported that Zonda exchange cannot access a cold wallet holding approximately 4,500 Bitcoin (BTC) worth about $334 million, as the platform faces surging customer withdrawal requests and allegations of insolvency. CEO Przemysław Kral stated that the private keys to the wallet were not transferred during a previous leadership change and attributed the issue to the 2022 disappearance of founder and former CEO Sylwester Suszek. Kral publicly disclosed the wallet address, denied any misappropriation of user funds, and assured that Zonda would fulfill its obligations to customers.

The inability to access the cold wallet was revealed amid abnormal withdrawal volumes, which Kral linked to negative media coverage. This follows weeks of local reporting about a legal probe in Poland targeting Zonda, ongoing blockchain analysis raising questions about the exchange’s solvency, and declines in Zonda’s hot wallet balances. The CEO announced a possible legal response to false claims and maintained that the company’s overall holdings remain intact, though the situation has raised concerns over asset recovery and investor protection.

The incident amplifies debate in Poland’s crypto sector over regulatory oversight and custody practices. The lost private keys and issues during leadership transition highlight risks facing investors on centralized platforms. Zonda’s crisis contributes to broader discussions about regulatory and management standards for crypto exchanges, driven by both technology vulnerabilities and company failures.
