Why can't I withdraw part of my balance?

Each asset in your account has two parts:

Your total balance is both parts added together. When you use your card, your rewards balance is used first, then your own funds.

So if you can see a balance but can't withdraw all of it, the difference is your rewards balance. Use it on your next card purchases.

Balance not updated? Only completed transactions count toward your balance. Pending ones are added once they complete.
