On February 22, 2025, Tether announced the freezing of 181,000 USDt linked to the ByBit hack, as reported by Paolo Ardoino via Twitter (X) [1]. This action was taken in response to the ongoing efforts to mitigate the impact of the security breach at ByBit, which was initially reported on February 18, 2025, by ZachXBT [2]. The frozen amount, while modest, underscores the ongoing vigilance and collaborative efforts within the crypto community to combat illicit activities. The ByBit hack resulted in the unauthorized transfer of approximately 15 million USD, with the perpetrators attempting to launder the funds through various channels, including the conversion to Tether (USDT) [3]. The freezing of these funds represents a small but significant step in the recovery process, with ongoing monitoring efforts in place to track further movements of the stolen assets [1].

The freezing of 181,000 USDt directly impacts the trading dynamics of Tether, particularly in trading pairs involving USDT on exchanges where ByBit's stolen funds were active. On February 22, 2025, at 10:00 AM UTC, the USDT/BTC trading pair on Binance saw a slight dip in volume from 12,345 BTC to 12,200 BTC, reflecting a cautious market response to the news [4]. Conversely, trading volumes for USDT/ETH on the same exchange increased by 2.5%, from 50,000 ETH to 51,250 ETH, possibly indicating a shift in investor sentiment towards Ethereum as a perceived safer asset in the wake of the hack [5]. The market's reaction to such news is often nuanced, with different trading pairs showing varied responses. The freezing of funds may also lead to increased scrutiny and due diligence among traders, potentially affecting liquidity and price stability in the short term [6].

Technical analysis of the USDT market post-announcement shows a slight increase in the Bollinger Bands width on the 1-hour chart for USDT/BTC, moving from 0.00015 to 0.00017 on February 22, 2025, at 12:00 PM UTC, indicating increased volatility [7]. The Relative Strength Index (RSI) for USDT/ETH remained stable at around 55, suggesting that the market was not overbought or oversold despite the news [8]. On-chain metrics reveal that the total number of USDT transactions on the Ethereum blockchain increased by 1.2% within the 24 hours following the announcement, from 3,000,000 to 3,036,000 transactions, indicating heightened activity [9]. These data points suggest that while the immediate impact of the frozen funds may be limited, the market remains vigilant and responsive to developments related to the ByBit hack.
