Regarding the post I made yesterday about the two coins being brushed, many people said they saw someone in the square get caught for several thousand U, saying that this kind of brushing shouldn't be done. What I want to say is that everything comes with risks; if you're afraid, don't do it. If you do it, don't be afraid. Getting caught is originally a low-probability event; even during normal brushing, you can still get caught. Moreover, did those who said it's not acceptable really read my post carefully? I mentioned in the post that I wanted to buy at 1030 U to brush, because this pool is shallow, and large amounts do carry certain risks. Small amounts are unlikely to get caught for several hundred or thousand U at once. Small amounts may only encounter losses caused by price drops. If you give up the high probability of a daily loss of about thirty percent out of fear of that extremely low probability of getting caught, then I have nothing to say; it's a personal choice, and I won't comment on it. Some people with a lot of negativity just can't reach the grapes and say they're sour. I'm just sharing a method; if you trust me, then give it a try; if you don't believe it, then don't try. It's a very simple matter. Also, I entered at 1030 today and exited at 1028.33, with a loss of 1.67 U, and including gas, it's less than 2 U.
