I completely agree, I tend to be too greedy every time and often plan ahead. For example, during this recent drop, I bought BNB at 900, halfway up the mountain. I think next time I can try Binance's trading insight feature. When the greed index reaches 10, I will buy when the bottom volume increases. At a greed index of 85, I will sell when the top volume increases. I will try this next time and see how some big players operate. They usually have their own jobs or travel, and they make a few trades at key points throughout the year.
