It's possible?
I make purchases of all the material in the company for which I work and I intend to remove my Indonesian supplier for another.
Are you trying to form some kind of boycotting because a certain supplier doesn't accept Bitcoin? I highly doubt that will ever become a reality. Remember that not even a majority of the world is using Bitcoin, and even if the majority was, the seller has no issue accepting any other form of currency as long as they have customers buying. Without buyers, it makes sense to ignore a certain type of currency, but all that matters to the seller is how easy it is to get it converted to whatever kind of currency the seller wants. Bitcoin may not be as easy to get converted to fiat, so the seller decided to not accept it. I don't see any issue in that, especially because he's running a business.
Agree with you here. The op must have lost his mind to make such a statement. Such behavior would only tend to hurt bitcoin and the crypto world which is not something I actively encourage. The fact as you stated is that majority of the world does not even know much about bitcoin(Forget about using it). It is our job as crypto professionals to help crypto newbies understand how bitcoin and altcoins can serve as great alternatives to FIAT currencies in the modern world today. We need to advertise bitcoin more actively in countries around the world to help people realize the value of this amazing coin.
