Positive public opinion 热度 (translated: public opinion heat) on social media and forums can create FOMO (fear of missing out) among investors. When many people are discussing and hyping a particular cryptocurrency, it can prompt new investors to enter the market and existing ones to increase their holdings, thus increasing demand and driving up the price. Negative public opinion can have the opposite effect, causing investors to sell.

It's important for investors to not only consider market trends and analysis, but also be aware of the influence of public opinion on cryptocurrency prices. Keeping a balanced view can help in making informed investment decisions.
