Authorities across multiple jurisdictions have moved against alleged cryptocurrency fraud operations this week, freezing assets, revoking licenses, and filing criminal charges against suspects accused of misappropriating millions in user funds.

A Tether-backed cryptocurrency exchange has frozen withdrawals after reporting that more than $7 million moved from custody to outside wallets, with recovery efforts still at an early stage, according to CryptoSlate. The platform has not disclosed whether the outflows resulted from a security breach, insider action, or other causes, but the freeze remains active as investigators work to trace the missing funds and determine the method of the unauthorized transfers.

In Australia, the financial intelligence agency AUSTRAC cancelled the registration of crypto provider GetCoins following customer complaints about alleged investment scams, CryptoSlate reported. The cancellation comes as part of an annual tally covering remittance and virtual asset providers, with authorities determining that GetCoins was allegedly exploited by investment scams targeting users. The revocation removes the firm’s legal authorization to operate as a registered crypto service provider in the jurisdiction, effectively halting its regulated activities pending further investigation.

Polish prosecutors have escalated their investigation into Zondacrypto, charging a fifth suspect in connection with the collapsed exchange formerly known as BitBay. Prosecutors charged Romana Ż. with organized crime and misappropriation offenses involving $2.1 million in user funds and are seeking pretrial detention, according to Cointelegraph. The exchange stopped trading in April after customers faced frozen withdrawals, with estimated losses of at least $94 million, CoinDesk reported. BitBay rebranded as Zondacrypto in 2021 before the platform’s recent collapse triggered the ongoing criminal probe, which now includes multiple defendants facing serious felony charges related to the suspected diversion of customer assets.

In Ukraine, police dismantled a criminal operation accused of stealing up to $1 million per month through cryptocurrency scams. Investigators have identified 62 victims and say more than 46 Ukrainians took part in the alleged operation, CoinDesk reported. Authorities did not specify the total amount stolen over the operation’s duration, but the monthly figure suggests significant cumulative losses distributed across the identified victim pool. The takedown represents one of the larger domestic enforcement actions against crypto-related fraud in the region, targeting an organized network rather than individual operators.
