I had dinner with friends today, but someone who trades in A-shares shared some experiences with me, not technical aspects, but psychological ones.

In trading, emphasizing your own broad vision is actually ignorance; the more inexperienced people are, the more they like to talk about having a big picture. If a relative asks you, "This stock is down 50%, what should I do?" what is most people's answer? They tell him to wait and see, since it's already at this point, open your mind—maybe by the end of the year, you'll break even. When it hits the stop-loss point, oh, they can't face the loss, no stop-loss, claiming that they "opened their mind." They think they need to have a big picture to make big money. But actually, the big picture is like a fancy package—you keep unwrapping it, and in the end, you find only two words inside: ignorance. They make a little profit and run, no big picture, hit the stop-loss point, no big picture after the stop-loss. For most people, they don't know when to have a big picture, they don't know why they need one. In the end, they ask themselves what they are doing and don't know, but they only know one thing: their big picture is right for themselves, their perspective is open. These people always have one belief—that is, if a friend has been investing for years and finally breaks even and even makes good money, it's like seeing a banner at a lottery shop that says, "This lottery shop has won 5 million," and you think the next winner will be you. You go crazy buying tickets at that shop. If you truly had a big picture, you should cut losses on time, follow your discipline—that's what having $BTC a big picture really means.
