Bank account for Montenegrin company outside of Montenegro ?

Does Wise and Revolut accept Montenegro? you may check, they are good options.

You can't fully trust any bank these days. Diversification is key, you need at least five accounts across different EMIs and banks to stay secure.

The three mentioned here in this thread might work well for some people, but could be a terrible fit for others.

Then I would suggest you to have a look here

Payset has working OK for me
The Kingdom Bank, didn't opened an account with them yet.
Worldfirst, regular goog EMI which works fine.
