These are used to trade for Special Theme cards during a Special Theme Event. You collect these along with Mileage when you draw cards in a limited-time draw.

It usually requires 800 Trade Coins to trade an XR Performance Card, this is equal to 8 times of X10 draws in an event.

Usually, you’re only allowed to trade for one card per group.

<aside> 💡 Trade coins will be removed after the duration of an event and you will not be reimbursed. Try to use them before the event ends.
