According to Miles Deutscher, recent Bitcoin (BTC) market movements show that while BTC rallies often result in only minimal gains for altcoins, significant BTC declines of around 5% trigger much sharper sell-offs in the altcoin market (source: Miles Deutscher on Twitter, May 24, 2025). Traders should note this asymmetric price behavior, as it highlights increased risk for altcoin holders during BTC downturns, emphasizing the importance of risk management and portfolio diversification in current crypto market conditions.
