What is investment really about? Has anyone thought carefully about this question? When you haven't thought carefully about this question, I suggest you do not participate in investments, especially in high-risk markets like cryptocurrencies. Personally, I believe that investment is about cognitive gaps and information gaps. Obtaining good investment target information ultimately determines your entry cost, while the level of cognition determines the size of the wealth you will ultimately reap. There is a saying in this field: buying well is not about being a master, selling well is what makes you a master. Encountering good targets early on comes from your luck and fortune, while how much wealth you ultimately gain comes from your cognition. Luck is an uncontrollable objective condition, while improving cognition is a subjective behavioral awareness. You can only have the opportunity to improve your cognition if you let go of past mindsets. If you had to choose between improving your cognition through repeated losses or through continuous learning, which way would you choose? Be grateful to those who inform you, and respect those who help you improve your cognition. Not everyone has the opportunity to stand on the shoulders of giants, so cherish it as you go.
