Best way to sell BSV and receive Euro on cards?

No idea.
I am in this dimention for BSV only.

What do you mean

Sorry.
I mean i did never sold BSV at this moment and don't use cards. I fact personaly here in West Belgium i always pay cash ( in euro) .
My wife has a small marketplace on secondhand online Belgium where she accepts BSV for living herbs that you only can get at my home( no sending by post).
I used only BSV directly on a few apps.
I hope others can give you the answer.
Have a beautiful day and good luck to you.
