The price of Bitcoin fluctuated today, rising to $87,453 in the early morning before dropping to $83,655 due to the impact of Trump's speech. Price fluctuations are influenced by multiple factors, including the Federal Reserve's monetary policy, the global economic situation, the behavior of institutional investors, market sentiment, and the regulatory environment. Technical analysis shows support around $86,000, but there is a risk of a pullback to $73,700. Short-term market sentiment is sensitive and easily affected by rumors. In the long term, Bitcoin's fundamentals remain strong, with global low interest rates and rising inflation expectations favorable for its development, but regulatory risks and market competition need to be continuously monitored. Investors should remain cautious, flexibly respond to market dynamics, and reasonably plan investment strategies to cope with uncertainty. Bitcoin has significant long-term growth potential, but changes in the macroeconomic environment, policy regulation, and technological advancements are key. Currently, the market's attitude towards Bitcoin is complex, and traders need to closely monitor information from various sources to make timely responses.
