According to Flood (@ThinkingUSD) on Twitter, traders should manage their portfolios as if every asset except Bitcoin is heading to zero, highlighting a risk-averse, Bitcoin-dominant strategy for 2025. This approach underscores a defensive position in crypto trading, especially during uncertain market conditions, and suggests focusing capital allocation primarily on BTC to minimize downside risk. Flood's statement is particularly relevant for derivatives traders on platforms like Hyperliquid, where quick market moves can amplify losses in altcoins (source: @ThinkingUSD, Twitter, April 28, 2025).
