@Maja10, @Dina18 There are two types of accounts: Payment Method and Payout Method.
The payment method is the account you use to pay for a reservation when you travel. The currency in which you pay is determined by the country where your payment account is located.
The payout method is the account into which you want to receive payments from guests staying at your listing.
Here are some links to help you understand the difference:

Hope this clarifies things for you!
