Currently, BTC has formed such a long shadow on the daily chart yesterday. In this market situation, it's not surprising to see such movements; it's merely the market makers washing out those high-leverage contract players.
Now, the weekend's market can basically be seen oscillating to digest the selling pressure, and the significant drop is also related to retail investors. The constant currency conversion in Mentougou can cause market panic, and then continuous price declines will further exacerbate this panic.
As a result, retail investors will follow suit and sell, leading to such a significant price drop. The weekend's market is mainly characterized by oscillation and slow growth, and then a new bullish trend will begin next week.
