As a seller, I currently accept:
Euro
Pound Sterling
US Dollar
What are the most useful currencies ?
All. I accept all of them.
Would I have more buyers if I had any other currency ?
Maybe 1, or few, but very few.
And you'll get PayPal conversion fees when you've been paid in HKD or
such that you wish to convert to EUR.
If you don't accept other currencies, PayPal automatically converts the amount
to EUR.
Or the buyer’s card issuer converts it which is always better than PayPal’s awful
exchange rate. That’s the buyer’s choice, I really wish to think that I don’t
miss any orders just because I accept EUR only. It’s 2025, exchanging currencies
should not be a problem unless you use PayPal to do so.
I'm not sure it's worth for a 'relatively small shop' (excuse
me) - as I'm not sure it's worth even for a bigger one - frankly
