One of the most common mistakes is 'chasing highs and selling lows.' When you see prices rising, you can't help but jump in, only to find yourself stuck at a high; when you see prices falling, you panic sell, missing out on the rebound. This kind of operation is like throwing money into water.

Another mistake is 'blindly following the crowd.' When you see someone recommending a certain coin, you buy in without doing any research, which often leads to being taken advantage of. Remember, information in the cryptocurrency world is mixed; you must have your own judgment and not blindly trust what others say.
