Bitcoin has been performing weakly recently, with market sentiment low. However, liquidity remains, and Bitcoin's market share is around 60.5%, which may lead to a brief rebound. Nevertheless, this round of the market seems to still be dominated by Ethereum.

Currently, investors should closely monitor the downward trend line. Only by breaking through this trend line and creating new highs can there be a possibility of reversing the current market trend.

The range of 120,500 to 120,900 USD remains a key resistance level, and breaking through this range will determine whether it can challenge new highs. On the other hand, the range of 115,700 to 115,300 USD has become a new support and resistance transition zone. As long as the price remains above this level, it will continue to test the trendline resistance.

It is worth noting that if the exchange rate experiences a rebound, it may lead to a slight increase in Bitcoin prices. However, whether this potential increase can be sustained still requires observation of more market factors.

Overall, the current Bitcoin market is at a critical moment. Investors need to remain vigilant and closely monitor changes in various key price levels, while also paying attention to the trends of other cryptocurrencies such as Ether, as they may have a significant impact on the entire cryptocurrency market. In this volatile market, rational analysis and cautious decision-making will be the keys to success.
