New Zonda CEO names missing founder as holder of BTC worth $336M

Zonda’s CEO says founder Sylwester Suszek failed to hand over private keys to a wallet holding ~4,500 BTC (roughly $336 million), last active in Nov 2025. The revelation, coupled with a Polish regulatory probe and negative media coverage, triggered an unusually large wave of withdrawal requests (over 25,000 around early April) versus ~100,000 annual withdrawals, raising solvency concerns and contagion risk for customer confidence. CEO Przemysław Kral denies misappropriation, points to a positive independent audit and says the firm will pursue legal action and meet obligations. Market impact: the episode increases exchange counterparty risk, can boost sell pressure or accelerated withdrawals from centralized venues, and may weigh on crypto market sentiment until keys or funds are recovered or regulators resolve the probe.
