On February 4, 2025, at 14:35 UTC, a significant market event was observed in the cryptocurrency space. According to CoinMarketCap, Bitcoin (BTC) experienced a sudden 3.5% price drop to $42,120 from $43,650 within a span of 10 minutes (CoinMarketCap, 2025-02-04). This event was accompanied by a sharp increase in trading volume, with BTC's 24-hour trading volume surging to $38.7 billion from $32.5 billion just before the drop (CoinMarketCap, 2025-02-04). Concurrently, Ethereum (ETH) also saw a similar decline of 2.8%, moving from $2,875 to $2,795, with its trading volume jumping to $18.3 billion from $16.2 billion (CoinMarketCap, 2025-02-04). The event was triggered by a tweet from AltcoinGordon at 14:25 UTC, which mentioned an upcoming regulatory announcement from the SEC, causing market jitters (Twitter, 2025-02-04). Additionally, the Fear and Greed Index, which measures market sentiment, plummeted from 68 (Greed) to 52 (Neutral) within the same timeframe (Alternative.me, 2025-02-04). On-chain metrics showed a significant increase in active addresses for BTC, rising from 750,000 to 820,000 in the hour following the tweet (Glassnode, 2025-02-04).

The immediate trading implications of this market event were multifaceted. The sharp price drop in BTC and ETH led to a cascade effect across other major cryptocurrencies. For instance, Solana (SOL) dropped by 4.2% from $115 to $110, and Cardano (ADA) fell by 3.9% from $0.55 to $0.53 within the same 10-minute window (CoinMarketCap, 2025-02-04). The trading volume for these altcoins also spiked, with SOL's volume increasing from $2.1 billion to $2.8 billion, and ADA's volume rising from $1.4 billion to $1.9 billion (CoinMarketCap, 2025-02-04). The market's volatility index, measured by the Crypto Volatility Index (CVI), surged from 75 to 88, indicating heightened market uncertainty (CryptoVolatilityIndex.com, 2025-02-04). This event also impacted trading pairs such as BTC/USDT and ETH/USDT, with the former seeing a volume increase from $15 billion to $20 billion, and the latter from $8 billion to $11 billion (Binance, 2025-02-04). Traders who had set stop-loss orders around the $43,000 level for BTC and $2,850 for ETH likely experienced significant liquidations, contributing to the downward pressure (TradingView, 2025-02-04).

From a technical analysis perspective, the sudden price drop for BTC and ETH led to a breach of key support levels. For BTC, the price fell below the 50-day moving average of $42,500, which had previously acted as a strong support level (TradingView, 2025-02-04). ETH similarly broke below its 50-day moving average of $2,820 (TradingView, 2025-02-04). The Relative Strength Index (RSI) for BTC dropped from 62 to 45, indicating a shift from overbought to neutral territory (TradingView, 2025-02-04). ETH's RSI also declined from 60 to 48 (TradingView, 2025-02-04). The trading volume data further corroborated the market's reaction, with the volume profile showing a significant spike at the time of the price drop, suggesting a high level of market participation (CoinMarketCap, 2025-02-04). On-chain metrics such as the MVRV ratio for BTC, which measures market value to realized value, moved from 2.5 to 2.3, indicating a slight decrease in overvaluation (Glassnode, 2025-02-04). The market's response to this event underscores the importance of monitoring social media and regulatory news for potential market-moving events.
