We can't deny the fact that Bitcoin is a great companion when it comes to trade involving a lot of a variety of commodities, as the case maybe, but rarely physical.
Have you ever purchased a physical commodity using Bitcoin? What's your experience?
Of course you can, it is quite easy in many countries. Cars and real estate are the most common purchases. You can look for sellers that are already willing to accept it or you can ask them. Often they won't want it, but sometimes someone will say yes. My experience with buying a car was pretty easy, I encountered no issues.
