Discuss several key points of the current market:

1. The main source of funds for this bull market is driven by American capital.

2. The United States is still in a holiday atmosphere (from Christmas to New Year), which has affected market liquidity to some extent.

3. It can be inferred that current market liquidity is not abundant, especially during weekends. We can observe that there is a negative premium between CB's BTC spot and BN, which further confirms the tight state of market liquidity.

Regarding today's Bitcoin market, a typical M-top pattern has emerged in the short term. However, it is important to note that this pattern is not suitable to be used alone as a basis for opening long or short positions. We need to consider the overall market state and find key positions within the pattern to formulate trading strategies.
