What is not insured by FDIC with my other PayPal accounts?

When you enroll in PayPal features that include pass-through insurance (currently only available to select U.S. customers in beta), funds held in USD will be eligible for FDIC coverage. FDIC insurance does not apply to any funds in your PayPal balance that are held in non-USD currencies. If you convert your PayPal Personal Account into a PayPal Business Account, your funds will no longer be held in our custodial accounts and will no longer be eligible to receive the benefit of FDIC pass-through insurance protection.
