As we all know, the primary driving force behind this bull market is American capital:
Currently, the U.S. is still in a holiday state (Christmas → New Year), which indicates that the current liquidity is very tight, especially on weekends.
From both the U.S. stock market and the cryptocurrency market, we can see that trading volume and volatility are relatively low. This kind of market situation is quite common at the end of the year, as there are a large number of deliveries, whether it’s selling off for the holiday or companies closing their books, so this drop can be considered reasonable and doesn't have a significant impact on the trend.
If you're interested, you can look back at past year-end markets, which are basically quite complicated; except for the monotonous upward trend in 2020, other years have shown a volatile market. The real breakthrough trends generally appear in January of the following year, so there's no need to overly focus on the market in these days, just stay calm.
As for whether altcoins can stand independently, there may be clearer observational results appearing between the end of this month and the beginning of next month.
