According to Charles Edwards (@caprioleio), questions are emerging about the validity of the Bitcoin Hash Ribbons indicator and the classic 4-year cycle, as well as the current state of altcoins. Edwards highlights that recent Bitcoin price action has diverged from historical recovery patterns typically signaled by Hash Ribbons, indicating a potential shift in traditional market cycles (source: Charles Edwards, Twitter, May 31, 2025). This raises trading concerns for both Bitcoin and altcoins, as traders may need to reconsider the reliability of these popular indicators for timing market entries and exits. The uncertainty in cycle predictability could lead to increased volatility and changes in capital rotation between Bitcoin and altcoins, making it essential for crypto market participants to reassess risk and strategy.
