According to Michaël van de Poppe (@CryptoMichNL), the traditional 4-year cycle for altcoins has been replaced by a set of evolving market variables. He notes that these variables are showing signs of improvement, suggesting that a significant breakout for altcoins is likely once Bitcoin surpasses its previous all-time high (ATH). For traders, this highlights a crucial trigger point in the cryptocurrency market, emphasizing the importance of monitoring Bitcoin’s price movements as a catalyst for altcoin rallies.
