Upon review: Previously, I placed an order at around 180 yuan and bought 4000 sol. It was when the pancake plummeted last month. The reason for buying was that I fell from 290 to 180 and felt that the drop was a bit too much, so I placed an order in advance and bought 180. When it rebounded to 220, it didn't come out. Then a few days ago, there was a sharp drop and the price dropped to 130, so I continued to buy 4000 sol. The reason for buying is that it feels oversold. In the morning, I sold all 8000 SOLs at a price of 173, with a net profit of approximately 16wu. 3. Nai Zi Ge is extremely not good at playing this mainstream currency band. I wanted to run at 175pm last night, but I couldn't figure it out myself. This morning, my friend told me that he had emptied half of the warehouse, and then Nai Zi Ge also ran away. The logic of running is just one, I feel that the current market liquidity is still too withered. 4. Key summary: This kind of gameplay is not within the ability range of Nai Zi Ge. Nai Zi Ge is really not good at it. Nai Zi Ge will imagine himself being very good at a certain trade, or in other words, buying and selling a certain currency high and low, and Nai Zi Ge will definitely be able to do it well. In fact, during the operation process, one's own feelings cannot deceive oneself. Not being good at it is not good at it. Don't fantasize about deceiving yourself. The transactions made by Nai Zi Ge are actually not as many as imagined. The truly frequent trading started after the end of 2021. In the past few years, more energy was still spent working. The cryptocurrency market is a place where feedback can be given quickly. It's too rare to quickly admit mistakes and think about how to make changes. By the way, I'm thinking about how to optimize and do better.
