The breakthrough of Bitcoin (BTC) at $99,000 is a historic milestone, indicating that the market's acceptance and confidence in cryptocurrencies are rapidly increasing. This may be influenced by multiple factors, including expectations of potential interest rate cuts in the United States, inflows into Bitcoin spot ETFs, and supply-demand changes brought about by the halving effect. Once the price surpasses this psychological barrier, it may attract more institutional and retail investors, creating a 'FOMO' (fear of missing out) sentiment. However, it is also important to be aware of the risks of a high-level pullback, as prices have surged too quickly in a short period, which could lead to bubbles or extreme volatility. Investors should carefully assess risks and manage funds and risk control.
