Gurhan Kiziloz, whose gaming operations generated substantial transaction volumes between 2021 and 2024, has been cut off from $213 million in cryptocurrency holdings following enforcement action by Brazilian tax authorities.
The asset freeze marks an escalation in regulatory scrutiny of gaming operators who processed payments through cryptocurrency channels. Tether, responding to Brazilian legal orders, has locked the funds pending resolution of claims involving tax compliance and token sale violations.

Kiziloz operated platforms that moved betting volumes through digital wallets during a period authorities now say involved systematic tax avoidance. The gaming operations continued throughout years when Brazilian regulators repeatedly sought clarification on tax obligations and licensing status.
Cryptocurrency token sales allegedly conducted alongside the gaming business have drawn separate regulatory attention. Authorities claim these offerings bypassed required registration processes, potentially exposing investors to unvetted securities.
The $213 million sits frozen across wallet addresses that investigators traced to Kiziloz’s operations. The funds cannot be moved, transferred, or accessed while enforcement proceedings continue. Tether maintains technical control over USDT tokens and can render them immovable when presented with valid legal orders.
This freeze represents a significant intervention in what had been a fluid financial situation for Kiziloz. Prior to the block, the funds remained accessible and deployable. Now they sit as frozen entries in blockchain ledgers—visible but unusable.
Brazilian authorities have pursued similar actions against other gaming operators, but the size of this freeze stands out. The $213 million figure suggests either substantial profits from the disputed period or accumulated reserves from operations authorities claim lacked proper tax treatment.
Tether has frozen substantial sums in 2025, with this case adding to a growing total. Earlier freezes included $180 million in separate matters. The company reports blocking more than $3 billion since implementing enforcement capabilities. The pattern suggests cryptocurrency’s regulatory environment has shifted from permissive to actively policed.
For Kiziloz, the freeze creates immediate financial constraints. The gaming operations that generated the frozen funds face questions about their legal status during the years in question. The token sales face allegations of securities violations. The resolution timeline remains unclear.
Regulatory proceedings are ongoing. No criminal charges have emerged, keeping the matter in civil enforcement territory. But the scale of frozen assets and the nature of allegations signal serious regulatory interest in the case.
Kiziloz remains unavailable for comment. No public defense of the gaming operations or token sales has emerged. The silence leaves only the regulatory allegations in the public record.
