Groupon is approximately one year older than Bitcoin. As an infant, a big fat toddler at that, I find it interesting that they are already jockeying for position to get their own key(s) on future cash registers.
My question is this: Should the Bitcoin cash register key have an alpaca or squirrel on it?
Seriously, who at/in/with Bitcoin would make this similar maneuver prior to Bitcoins going mainstream? It's an almost given that Bitcoin, within ten years, will have its own key(s), simply due to reaching its critical mass. It can easily happen without any needed intervention. Whereas Groupon opted to have a key created as a marketing ploy to garner further retail(er) interest.
Understandably, it's way to early to discuss a Bitcoin cash register key. Or is it? Facebook Credits are coming to mobile operating systems: http://www.digitaltrends.com/social-media/insiders-confirm-facebook-credits-are-coming-to-mobile-operating-systems/Bitcoin: Tomorrow's Currency Today
