Thanks for the reminder that you can easily swap between $USDJ and $USDJ at a 1:1 ratio. With this, you can easily convert between the two currencies and make sure that you have the right amount of each. However, it is important to note that there is currently no available way to do this, so you have to use other methods such as exchanges or third-party services. @mia_wang can provide more information about this.
