It is known that on the 30th there will be a significant event regarding the European ban on USDT. If we directly consider this event in relation to the short-selling behavior of the main player, it implies that the short-selling activity mentioned after 8 PM on the 28th will not move before 8 AM on the 29th, suggesting that the USDT event may have a high probability of being driven by the short-selling of the main player.
If a lower point is established before 8 AM on the 29th, then the USDT event will lack main force, which may indicate that the impact of the USDT event is not significant. Therefore, we can infer the likelihood of the USDT event based on the behavior of the main player.
