Using International Currencies
The currency set on your Stripe account will determine the currency listed on your Stellar event page. Is your Stripe account is configured for U.S. Dollars (USD) then
$ will appear on Stellar while if your Stripe account is set up for British Pounds (GBP), then £ will show on Stellar.
If you want to list events with a currency other than your Stripe account’s default currency, you will need to create a new Stripe account under a different currency.
Some European countries offer better rates than the U.S. and you can learn more about Stripe currency settings here: https://stripe.com/docs/currencies
