 Now, I bought it at 5.1K around February 23, and have been holding it ever since. After bottoming out at 4K in November 2022, it soared to 7K in December 2022, a month later, and was adjusted to the 5-6K level for 6 months until May 23, taking a break to accumulate listings and rise again during that period. The price fell for three months until September 23, but the long-term 200-day line turned upward after several years of long decline. It met the falling price range in September 2023 and reached bottom.
