It sounds very cool, because it puts the bitcoin payment system to a whole other level. If further the cryptocurrency will be accepted as now, then the time will come when we will have no problem paying for groceries or if we do repairs, we buy for example
glass doors, just by paying with a bitcoin card. That's what my brother did recently, when he bought doors and windows for his house. Hopefully soon politicians will come to debates and make a decision to legalize cryptocurrency.
