To withdraw, your identity must be verified and two-factor authentication must be on.
Open Wallet, then Withdraw, enter the destination address and the amount, and select Review withdrawal. Check the fee, the total that will be set aside (Total deducted, or Maximum reserved) and what you receive, then select Confirm withdrawal. If your last authenticator confirmation is not recent, you are asked for a code right there; you stay signed in and the same request continues.
Withdrawals are paid from the available balance of your Spot account. The minimum withdrawal is shown in the form. Limits apply to each withdrawal, to your total over 24 hours and to the number of requests per hour; if a request is over a limit, the message tells you which one. A FALKR address can't be used as a destination. Once submitted, a withdrawal can't be cancelled from your account, so check the address carefully.
