Looks like they will try to reverse the trades. But I'm now sure how that's going to work because the "hacking" rumors and all the "irregular trades" made the price of everything to tank.
From Binance's CEO:
"All funds are safe. There were irregularities in trading activity, automatic alarms triggered. Some accounts may have been compromised by phishing from before. We are still investigating. All funds are safe."
