Binance.US publishes 6 separate rules that stop a withdrawal. Each one is triggered by something you did, and each has its own length and its own scope — which is why "my account is locked" is usually the wrong description of what is happening.
Only the amount you deposited or bought is held — the rest of your balance still moves
✔You can trade right now
✕Cannot be shortened, including by support.
Exactly 168 hours from when the deposit was initiated — a deposit at 3:00 PM Monday unlocks at 3:00 PM the following Monday. Binance.US states there are no exceptions.
Holds run on a timer, not on a decision, and no support agent has a button for them. Anyone who contacts you offering to release your funds early — by any channel, for any fee — is running a scam. Binance.US will never ask you to pay to unlock your own balance.
