Bitcoin surged to around 102,500 last night, close to the upper end of the range of 103,000 mentioned before. I also said in my post last night that when approaching the upper end, one should not chase long positions, but rather close out long positions and consider opening short positions near the upper end price. The so-called volatile market refers to prices jumping back and forth within a range. The volatility range has been mentioned many times before, which is between 94,000 and 103,000. At the top and bottom of the range, one should buy low and sell high. After making this range judgment, the price touched around 94,000 twice and surged to around 103,000 once. There are actually three or four low-risk trading opportunities each week, which is quite good, and the profits from each trade can be considerable. If you are not satisfied with Bitcoin's return rate, you can actually refer to Bitcoin's high and low points to trade other more volatile cryptocurrencies, which will greatly amplify the returns. This kind of operation is generally only advised for small positions. Generally speaking, I would recommend trading Bitcoin unless there are opportunities for other cryptocurrencies to catch up or decline relative to Bitcoin. Although Bitcoin's volatility is not that high, its price trends are relatively more regular and easier to predict, making it suitable for larger positions with less chance of unexpected and uncontrollable risks. Currently, the price is at a middle position, so it is not advisable to open new positions. Instead, it is recommended to close some short positions and keep a portion.
