I finally found this one in August. Two months after it was issued, Ethereum happened to rise to the daily line of 200ma and began to sell down three times. At the sub-level, 1680 became the first sell. It is still within the two-sell center at the sub-level, and it fell. If it breaks 1073, it will exit the central departure period and confirm the second sale. Therefore, the downward trend is not over yet.
