Most of the time, it's like a person knowing the warmth or coldness of drinking water. When I thought Bitcoin was digital gold, I was surrounded by the Air Force. When I bought it all the way at an average price of 77500, it dropped by 74000. At this moment, there are many people around me who are looking at 60000, 50000, or even 30000, and those who have been following my Twitter for a long time should be able to feel it. I have been reflecting recently. Are these people who have risen and fallen higher and lower really wrong? Am I really right to get 90000? It seems that it's not necessarily the case. Most of them trade according to the trend, and if they strictly take profit and stop loss, the long-term PNL may not necessarily be low. For example, my operations in the US stock market are relatively like this, but as someone who keeps buying BTC without setting a stop loss, I just haven't encountered a darker black swan. The investment road is long, and whether I win or lose, it is always short-lived. No matter how prosperous it is, it really needs to be optimized.
