Squatting one, what should I do about this, it directly disappeared by half?? What’s the reason?

Brothers participating in Binance's alpha event to boost trading volume, be very careful from now on. In my non-custodial wallet on Binance, when interacting with zkj, after continuously making 12 transactions, I exchanged 1081U for 536 zkj, and then exchanged back to U for 455U. This happened during the continuous interactions, and you can see the transaction times of the previous few transactions. It's hard to guard against!
