Can I use Bitcoin as collateral for USAA personal loans?
USAA does not currently offer secured personal loans, though they used to. Right now, you can only apply for an unsecured perosnal loan, which does not require any collateral. When USAA used to offer secured personal loans, the only type of collateral they accepted was a vehicle. So if USAA secured loans come back, it's likely you will not be able to use Bitcoin as collateral.
