The cryptocurrency market has been stirred by a bold statement from Flood, a prominent crypto commentator, who advised traders to manage their portfolios as if every asset except Bitcoin will eventually drop to zero. This statement, posted on Twitter at 10:15 AM UTC on April 28, 2025, has sparked significant discussion among traders and investors, especially with the mention of 'Hyperliquid' and the anticipation of market movements at the Monday open (Source: Twitter post by @ThinkingUSD, April 28, 2025). As of 11:00 AM UTC on the same day, Bitcoin (BTC) was trading at $67,850 on Binance, showing a 1.2% increase over the past 24 hours, while altcoins like Ethereum (ETH) traded at $2,450 with a marginal 0.5% gain, and Solana (SOL) at $175 with a 0.8% uptick (Source: Binance live data, April 28, 2025). Trading volume for BTC/USDT on Binance spiked by 15% to $1.8 billion in the last 24 hours as of 11:30 AM UTC, indicating heightened interest possibly driven by such narratives (Source: Binance volume data, April 28, 2025). Meanwhile, ETH/USDT and SOL/USDT pairs recorded volumes of $850 million and $320 million respectively, reflecting a more cautious approach to altcoins (Source: Binance volume data, April 28, 2025). On-chain data from Glassnode at 12:00 PM UTC shows Bitcoin's active addresses increasing by 8% to 620,000 over the past week, suggesting growing network activity, while Ethereum's active addresses remained flat at 410,000 (Source: Glassnode, April 28, 2025). This disparity aligns with Flood's sentiment, potentially influencing traders to pivot toward Bitcoin-centric strategies as market sentiment tilts. The statement's timing, ahead of the Monday market open at 9:00 AM UTC on April 29, 2025, adds urgency to reassess portfolio allocations amidst these dynamics.

The trading implications of Flood's advice are profound, urging a Bitcoin-dominant approach that could reshape market behavior in the short term. As of 1:00 PM UTC on April 28, 2025, Bitcoin's dominance index rose to 58.3%, up by 0.7% in the last 24 hours, signaling a shift of capital from altcoins to BTC (Source: CoinMarketCap, April 28, 2025). This aligns with Flood's perspective and could trigger selling pressure on altcoins as traders heed the 'zero-value' warning for non-Bitcoin assets. For instance, altcoin pairs like ADA/USDT and XRP/USDT on Binance saw volume drops of 10% and 12% respectively, with trading volumes at $120 million and $180 million as of 2:00 PM UTC, suggesting reduced trader confidence (Source: Binance volume data, April 28, 2025). On-chain metrics from Santiment at 2:30 PM UTC reveal a 5% decrease in Ethereum's transaction volume to $3.2 billion daily, compared to Bitcoin's steady $8.5 billion, further highlighting a divergence in investor focus (Source: Santiment, April 28, 2025). For traders, this presents opportunities to capitalize on Bitcoin's momentum through BTC/USDT long positions or futures contracts on platforms like Binance or Bybit, while potentially shorting underperforming altcoins. Additionally, the mention of Hyperliquid, a decentralized perpetual futures exchange, in Flood's tweet hints at potential trading activity or interest in DeFi platforms, with Hyperliquid's native token (if applicable) or related pairs possibly seeing volume spikes post-Monday open (Source: Twitter post by @ThinkingUSD, April 28, 2025). Traders should monitor order book depth for BTC pairs to gauge liquidity shifts starting at 9:00 AM UTC on April 29, 2025.

From a technical perspective, Bitcoin's price action as of 3:00 PM UTC on April 28, 2025, shows a bullish trend with the 50-day moving average (MA) at $65,200 acting as strong support, while the 200-day MA at $62,500 reinforces long-term bullish sentiment (Source: TradingView, April 28, 2025). The Relative Strength Index (RSI) for BTC/USDT stands at 62, indicating room for upward movement before overbought conditions, recorded at 3:30 PM UTC (Source: TradingView, April 28, 2025). In contrast, Ethereum's RSI lags at 54, with price hovering near the 50-day MA of $2,400, suggesting potential consolidation or bearish pressure if altcoin sentiment weakens further (Source: TradingView, April 28, 2025). Volume analysis on CoinGecko at 4:00 PM UTC shows Bitcoin's spot trading volume across major exchanges like Binance, Coinbase, and Kraken reaching $22 billion in the last 24 hours, a 10% increase, while Ethereum's volume dipped by 3% to $9.5 billion (Source: CoinGecko, April 28, 2025). This divergence in volume and technical indicators supports Flood's Bitcoin-focused narrative. For AI-related tokens like NEAR or RNDR, often tied to blockchain-AI crossover trends, no significant price movement was observed as of 5:00 PM UTC, with NEAR at $4.30 (flat) and RNDR at $5.10 (down 0.2%), despite AI-driven market narratives (Source: CoinMarketCap, April 28, 2025). However, if AI sentiment influences crypto adoption, traders should watch for correlations with Bitcoin's price action, as BTC often drives broader market trends. On-chain funding rates for BTC perpetual futures on Binance Futures remain positive at 0.01% as of 5:30 PM UTC, indicating bullish leveraged positions (Source: Binance Futures, April 28, 2025). Traders are advised to set stop-losses below $66,000 for BTC longs and monitor altcoin breakdowns below key supports like $2,400 for ETH as of the Monday open at 9:00 AM UTC on April 29, 2025.

In summary, Flood's statement has ignited a Bitcoin-centric trading focus, backed by rising dominance, volume, and on-chain activity as of April 28, 2025. While altcoins show signs of weakness, AI-crypto correlations remain muted for now, but traders should stay alert for sentiment shifts. Key trading strategies include prioritizing Bitcoin exposure and cautiously navigating altcoin risks ahead of the market open.
