This place is not to be underestimated. Clearly, they've built a lot of short positions, but from time to time, they push up the price to force other shorts out. The brother is not a deity; I can only see that he has built short positions, but I can't know when he plans to do a malicious short squeeze 😥

Now the price has dropped back again. If you want to short, at least push the price up a bit. You just rush up and then gradually drop to torment the retail investors, right? It's a bit of an ugly sight.
