Recent events such as the Bybit hack may impact the entire cryptocurrency market, triggering panic among investors and leading to a decline in confidence in cryptocurrencies. However, following the Bybit hack, the Fear and Greed Index did not experience a significant drop, which is worth exploring. On one hand, the market may have developed a certain level of resilience to similar events. The cryptocurrency market has experienced multiple hacking incidents in the past, and over time, investors' reactions to such sudden events have become less intense. On the other hand, the current market is highly focused on positive factors such as the approval of the LTC coin ETF, and these optimistic expectations have somewhat offset the negative impacts of the Bybit incident, preventing investor sentiment from falling into excessive panic. Furthermore, the investor structure in the cryptocurrency market is gradually diversifying; some long-term and institutional investors may prioritize fundamentals and long-term trends, and are less likely to change their investment strategies due to short-term emergencies. This has also stabilized market sentiment, keeping the Fear and Greed Index relatively stable.
