It makes sense that a transition to accept bitcoin would be underway for more US-based stores.
I think more retailers will accept bitcoin as a way of payment for about 5-10 years from now. It will take a long time because bitcoin is not yet famous around the world. Most of the countries have fewer knowledge about bitcoin thats why they cant cope up with it especially the retailers.
