Market Analysis on March 13th at Noon: Observing BTC's 4-hour chart, the price is operating above the middle band of the Bollinger Bands, and the middle band shows a slight upward trend, which may indicate that the market has some rebound potential. However, it is worth noting that the upper and lower bands of the Bollinger Bands are gradually converging, indicating that the price's volatility range is shrinking, and the forces of both bulls and bears are currently in a relatively balanced state. Based on this, we plan to conduct a short-term operation in the afternoon. Short-term operation suggestions are as follows: BTC: Buy on dips in the range of 82300-82800, setting a target price at 84000-84500, while setting 82000 as the stop-loss point. ETH: Similarly, in the range of 1850-1870, it is recommended to buy on dips, targeting 1950-2000, with 1830 as the defensive point.
