The startup phase of a bull market is often accompanied by an increase in Bitcoin's market share, as funds during this phase flow more towards Bitcoin, the core asset of the market, while the performance of other tokens lags behind. When Bitcoin's market share reaches its peak, market liquidity and investor sentiment are often close to a critical point. At this time, investors begin to take profits, and Bitcoin's market share subsequently declines, with funds gradually shifting towards altcoins, forming what is known as the altcoin season. The current market is transitioning into this phase.
