In case of any incident or change in security or an attempt to hack Binance, stop payment and selling operations for 24 hours

I tried to open my account on the laptop, but it didn't open, so I went back to my phone and found all my currencies sold and converted to BTC, but I still can't convert them to USDT, nor can I use them, nor do I know what to do. Please, whoever knows the solution, help me.
