Binance temporarily suspended withdrawals because users complaind of unconsented trades into BTC from their alt positions.
The rumoers was that binance was hacked. But that's not what happened. The USERS were hacked by the third party bot they were using that tried to fk them.
So binance stopped withdrawals to prevent these users from losing money from their accounts via malicious bot sending the money elsewhere.
moral of the story: watch which 3rd party trading software you're relying on.
