The most fundamental difference between a bull market and a bear market is trend and sentiment.

Large capital volume, active trading, and frequent liquidations are precisely the signs of extreme market enthusiasm and intense battles between bullish and bearish sides, which are often seen during the upward phase of a bull market.
In a bear market, the underlying market sentiment is fear and despair. Investors generally tend to exit rather than enter. Funds are continuously flowing out, not actively engaged in battles.
So, if you see that the exchange chat rooms are still lively and many people are chatting overnight, it indicates that the market is still healthy. If one day the chat groups are silent or only a few people are talking, it instead suggests that a bear market has arrived. #美联储降息预测
