Josip Hi 👋 there,
I am not sure why you need a USD account.
If you just need to receive USD an then convert them to EUR, a cheaper way is to use Wise which for outgoing payments is fully integrated with bunq and for in coming just requires some set up in Wise App itself.
Wise has the cheapest costs in terms of no SWIFT charges and best conversion rates ✅
Cheers 🌈
