I see that several cryptos will be in the EU beta release. Do you have any ideas on what coins will be added to the Live Release? 
Will some coins be easier to add than others based on the technical details of the specific chain?

The white paper mentions rounding up purchases (presumably up to the nearest Euro) with the user being able to route the rounded up amount elsewhere, like a “crypto trading account.” Do you know what exchanges will be available to send this round up? Is this done via an exchange integration/API, or wallet address (potentially a separate non exchange wallet?)
