I have cash (US$, GBP, CHF and some exotic currency) from my old trip. So if someone have interest, I can propose you an exchange : I give you my cash and you make me a transfert to my Revolut card. It’s totally free for us and we have both advantage : you can use the cash in your country or during your trip and I can buy in Internet with my currency.
I’m in France near Germany. I still travel a lot. If someone have any interest, send me a message.
