Yes. Meeting Truth allows you to choose a currency when you set up your tickets for an event.
Once you're upgraded to a Premier or Business PayPal account, PayPal will let you accept different currencies. If you receive a payment in a currency that you don't have a balance account for, you will have the option of either creating a new balance account for that payment, or converting the payment to a currency that you do have an account balance for. Choose the option to create the new balance account if you don't want to incur currency conversion charges.
