What do you want to be added or improved?

As a user I want to add a area to turn the foreign currency to the account setting

Why do you need it?

• It's inconvenient that every time travel to other countries need to open a new account for their currency.

How do you imagine it?

As the photo I want the 'HKD' can be changed to other currencies and also have a online offline exchange rate
