Market analyst Ben Cowen highlights that a significant purge of speculative 'junk coins' has been underway since 2021 and is crucial for a lasting Bitcoin bull market. Bitcoin dominance has risen above 60% as capital exits failed altcoins and memecoins, with expectations it could reach 70% by 2030. Despite Bitcoin's recent surge above $81,000, experts warn this may be a temporary rally before a potential pullback, emphasizing the need for this cleansing phase before Bitcoin can sustain a new bull cycle. The purge reflects a market shift where weaker projects fail, consolidating capital into Bitcoin or sidelining it until clearer bullish signals emerge.
