Polish prosecutors have charged a fifth suspect in their investigation into cryptocurrency exchange Zondacrypto, a case that centres on estimated losses of around $100 million.

The suspect, identified as Roman Ż., was arrested on Sept. 5 and now faces two offenses, according to prosecutors. He is the fifth person to be charged in connection with the probe.

Details of the specific charges against Roman Ż., along with the identities and roles of the other four suspects already charged, have not been disclosed. Prosecutors have not released further information on how the alleged losses were incurred or the mechanics of the scheme under investigation.

A widening investigation

The addition of a fifth charged suspect signals that the inquiry into Zondacrypto continues to expand months after it began. The scale of the estimated losses, at roughly $100 million, places the case among the more significant crypto-related fraud investigations to emerge from Poland in recent years.

For a European audience watching the crypto sector's regulatory trajectory, the case underscores the exposure that national prosecutors face when domestic exchanges are implicated in large-scale losses, even as the European Union moves to harmonise oversight of digital asset markets under its Markets in Crypto-Assets framework.

No further details on the charges, the alleged conduct, or the timeline for further proceedings have been made public by Polish authorities at this stage.
