Is there a way to buy it in advance and use it later when the exchange rate is low?

Shopping

I bought it in advance when the dollar or yen exchange rate was lowA

Is there a way to take it out and use it comfortably when you want to use it later?

I thought it would be too much trouble to go to the bank and store it, so

I was wondering if there was a convenient way to do this.

Do you have an app or something?

I can't see it in the bank app
