Btw, what's the point to use Bitcoin-based debit cards? To convert bitcoins into dollars? Nonsense. Bitcoiners would better focus on encouraging others to accept bitcoins.
Acquiring millions of merchants while convincing them to accept a new currency, a new method of accepting payment, and a new process for financial settlement is a major undertaking. It took VISA several decades before they ever realized a small profit.
Think of it like a revolutionary new type of engine--does it make sense to spend millions of Bitcoin to lay thousands of miles of brand new "rails" all over the world for your new engine to run on? A more sensible approach is to use your new engine on the existing "rails" that are already established in a massive network all over the world. Once you have a substantial volume of traffic, switching merchants to alternative rails becomes a viable option.
