Can you provide your BTC address of deposit for reference to total amount? I mean with that much BTC in an account, I would be appreciative of the extra caution before just releasing the funds.
Can you provide a binance support ticket number for reference or responses from the support staff?
You cant withdraw more than 2 btc a day without KYC... why would you be able to access 1200 btc without it?
That same question i have in mind mate,because 12 thousands bitcoin is a huge amount just to put in exchange without KYC ,i believe this is same reason why binance are investigating about your investments
Even my simple brain asking about fishy thing on this matter but I dont wanna give false judgement but i hope OP will be cleared on this one
