"Even just supporting the Euro zone will already be good progress, as it covers most of the wealth in Europe."

The point I was making was that even if Stripe supported the Eurozone countries, that could have it's own problems too. That probably wasn't too clear. The Euro could well slide massively in value versus the dollar which could impact Stripe's expansion to Europe, as there is huge uncertainty about the Euro here at the moment. I mean would you look forward to expanding to a region whose currency could actually collapse?
