Glassnode co-founders Jan Happel and Yann Allemann suggest that altcoins may soon outperform Bitcoin, contingent on Bitcoin consolidating above $100,000. They note a bearish flip in Bitcoin dominance, which could set the stage for a Christmas rally in altcoins, while long-term holders are nearing the end of their selling pressure. Currently, Bitcoin is trading at $101,893, with significant selling attributed to profit-taking and liquidations.
