In a Bear Market, waiting for a Rebound to exit, and in a bull run, waiting for a pullback to enter, this mindset is not advisable! If you have this mentality, you basically won't make any money. Let me give my buddy an example: in a Bear Market, if you bought Bitcoin with 100,000 USD to catch a falling knife, and it dropped to 50,000 USD, thinking you would wait for it to rebound before exiting, you will generally end up waiting until it hits a 50% Slump, getting trapped deeper and deeper until you don't want to look at your account anymore. And in a bull run, when it was 60,000 USD, you didn't dare to buy, thinking of waiting for a pullback to 20,000 USD, but it kept rising to 150,000 USD, 150,000 USD! Remember, recognizing the direction is the most important; once the big trend goes down, don't wait for a rebound, exit decisively. Once the big trend goes up, don't wait for a pullback, enter decisively!
