On weekdays, if the US stock market is closed, BTC liquidity often tends to be low like on weekends, and this phenomenon needs to be analyzed in more detail.

BTC price fluctuations are mainly driven by the trends of the US stock market, macroeconomic factors, and fundamentals. The performance of altcoins is more reliant on the upward or consolidation trends of BTC, and their market movements are usually driven by the liquidity of market makers.

As a result, there may be a time lag between the peaks of BTC and altcoins, with BTC usually peaking before altcoins. This aligns with the actual market situation, where when BTC prices peak, altcoins may continue to rise, attracting people to chase the high, which could eventually lead to being harvested at the peak.
