The global prominent cryptocurrency issuing institution, Tether, has recently taken urgent actions by freezing two Ethereum addresses, involving a huge amount of 1.56 million USDC. According to the real-time data provided by the MistTrack platform, the event happened just two hours ago. The two frozen addresses have interacted with numerous famous trading platforms in the last year, such as Binance, FixedFloat, and HitBTC. This freezing operation might be due to responding to unusual activities or potential security threats.
