Summary

Sylwester Suszek founded the Polish cryptocurrency exchange BitBay in 2014, which was later sold, rebranded as Zonda and then Zondacrypto, and collapsed in April 2026 amid an alleged large-scale fraud and money-laundering scheme affecting hundreds of customers and losses reported in the hundreds of millions of euros. Suszek disappeared on March 10, 2022, and has not been found; Polish prosecutors allege he alone held the private key to a roughly 4,500 BTC cold wallet that the exchange's later management said it could not access, a central element of the collapse. In July 2026, Polish prosecutors merged the criminal probe into his disappearance with the Zondacrypto fraud investigation, which by late 2026 had expanded into a dedicated seven-prosecutor national team and drawn in allegations about Polish political figures.
