I wouldn't fall back to USD. Neither of the accounts we looked at which had problems used USD. I would prefer to show an error or warning so that the site owner fixed it on the block.

There is an "error" already with the "unknown currency". And the issue is facing the end-users, which would not be really user-friendly... What is the issue with setting the default currency as 'USD'?

This is so outdated. I'll close it, as I am not sure this is still relevant.
