$BTC Down, I should consider the main influencing factors in the current cryptocurrency market. For example, the price trends of Bitcoin, the upgrade status of Ethereum, regulatory dynamics, and the performance of major altcoins. Additionally, macroeconomic factors such as the Federal Reserve's policies and inflation data may also affect market sentiment.

Then, I need to collect some specific data. For instance, has Bitcoin recently broken through key resistance levels? Are there any movements from institutional investors? What is the progress of Ethereum's Shanghai upgrade, and what impact does it have on the market? In terms of regulation, are there any new bills or policies being introduced, such as the SEC's lawsuit outcome against a certain project?
