So between B&N's numbers, Apple's close market share to them and everyone else (Google Play, Kobo, subscriptions, etc), I am going to argue that there is at least a billion -
dollar market everywhere beside Amazon internationally, and I believe that this is a very conservative number.
Over the past 6 months, the
market cap of the cryptocurrency space has been a gut - churning rollercoaster ride from one hundred to eight hundred billion
dollars and
everywhere in between.
