I am very happy with your idea. this will make it easier for bitcoin holders when buying goods online. moreover this will make everyone know about bitcoin. because not a few also people who do not know about this digital currency.
The main purpose of bitcoin is this that you use it for your shopping online and pay them from your blockchain wallet. Bitcoin is not for earning money as many people think of, but actually bitcoin is for use as your regular currency. When you use your bitcoin, demand fir it will increase and more people will buy bitcoin to use it for their shopping. By this way it will prevail in the world.
