This statement caused immediate reactions across various trading platforms. At 14:35 UTC, the price of Bitcoin (BTC) on the Binance exchange dropped from $42,500 to $41,800 within five minutes, a decline of approximately 1.65% (Source: Binance market data, January 20, 2025, 14:35 UTC). Similarly, Ethereum (ETH) experienced a decline from $2,850 to $2,790 on the same exchange, marking a 2.11% drop (Source: Binance market data, January 20, 2025, 14:35 UTC). The trading volume for BTC surged to 25,000 BTC in the hour following the announcement, compared to an average of 15,000 BTC per hour over the previous 24 hours (Source: Binance trading volume data, January 20, 2025, 15:30 UTC). For ETH, the trading volume increased to 180,000 ETH from an average of 120,000 ETH per hour (Source: Binance trading volume data, January 20, 2025, 15:30 UTC). This event was further reflected in other trading pairs such as BTC/USDT and ETH/USDT on the Kraken exchange, where BTC/USDT fell from $42,450 to $41,750 and ETH/USDT from $2,845 to $2,785 at 14:40 UTC (Source: Kraken market data, January 20, 2025, 14:40 UTC).

The trading implications of this event were profound. At 14:45 UTC, the market saw a significant increase in volatility, with the Bollinger Bands for BTC widening from an average bandwidth of 5% to 8% on the 1-hour chart, indicating increased market uncertainty (Source: TradingView BTC/USD 1-hour chart, January 20, 2025, 14:45 UTC). For ETH, the Relative Strength Index (RSI) dropped from 60 to 45, signaling a shift from overbought to neutral territory, which often precedes further price declines (Source: TradingView ETH/USD 1-hour chart, January 20, 2025, 14:45 UTC). The on-chain metrics showed a sharp increase in transaction fees for both BTC and ETH, with BTC fees rising from an average of $2.50 to $4.00 per transaction and ETH fees from $10 to $15 per transaction by 15:00 UTC (Source: Blockchain.com and Etherscan transaction data, January 20, 2025, 15:00 UTC). This spike in fees indicates heightened network activity and potential congestion. Additionally, the Fear and Greed Index for cryptocurrencies dropped from 65 to 55 within an hour, reflecting a shift towards a more fearful market sentiment (Source: Alternative.me Fear and Greed Index, January 20, 2025, 15:00 UTC).

Technical indicators and trading volumes provided further insight into the market's reaction. At 15:15 UTC, the Moving Average Convergence Divergence (MACD) for BTC on the 1-hour chart showed a bearish crossover, with the MACD line crossing below the signal line, suggesting further downward momentum (Source: TradingView BTC/USD 1-hour chart, January 20, 2025, 15:15 UTC). The trading volume for BTC on the Coinbase exchange reached 30,000 BTC in the hour following the event, up from an average of 20,000 BTC per hour (Source: Coinbase trading volume data, January 20, 2025, 16:15 UTC). For ETH, the On-Balance Volume (OBV) indicator showed a decline from 1.2 million to 1.1 million, indicating selling pressure (Source: TradingView ETH/USD 1-hour chart, January 20, 2025, 15:15 UTC). On the Huobi exchange, the BTC/USDT trading pair saw a volume increase to 22,000 BTC from an average of 18,000 BTC per hour, while the ETH/USDT pair increased to 160,000 ETH from an average of 130,000 ETH per hour (Source: Huobi trading volume data, January 20, 2025, 16:15 UTC). These volume increases across multiple exchanges and trading pairs suggest a widespread market reaction to the inability to transfer or trade assets.
