A very good read. It would be nice to have a more in depth view of several cards that are out there. It would be especially nice to know more about the fees and exchange rates, which is where they have an opportunity to take advantage of people.
I met the owner / founder of xapo at one of the first bitcoin meetings when it was around ten dollars per, and he was worse than a used car salesman, not a nice person. I have been waiting for a card that could be used internationally, but I will not give my business to xapo unless it is bought out by someone reputable.
