I wonder how they’ll do that. Recognize both currencies (new national and Euros)?
I think that all of these nation will return to the old currencies, leaving the Euro as a worthwhile experiment that did not work out. I think the Euro will cease to exist.
I don’t know enough about currency markets to be able to judge what each of their currencies would be worth on day one.
Had a rumor thread yesterday that said Germany was going to leave the Euro.
