The cryptocurrency market often experiences cyclical changes, with Bitcoin leading the rise first, followed by altcoins. Investors seek additional returns from newly gained market profits, leading to capital flowing into altcoins, which triggers a sharp rebound in a short period. Currently, Bitcoin is experiencing one of its worst Decembers to date, dimming the seasonal bull market period, having dropped 2% over the past 30 days. Due to profit-taking and cautious sentiment after weeks of price volatility, hopes for a 'Santa rally'—the phenomenon where assets tend to rise during Christmas week—may have been shattered. Some warn that, with the Federal Reserve indicating a reduction in rate cuts next year and emphasizing that it does not seek a national Bitcoin reserve, Bitcoin may face further declines. (Coindesk)
