Let put ourselves on the shoe of the owner. In my cognitive evaluation on veracity of bitcoin popularity and numbers there is a big market if I do accept bitcoin as payment and option for a better marketing strategy but the government is not declaring it legal and how would do I compute the taxation.
It is a good sign for bitcoin prevailing in the world. when all the restaurants, shops, markets of different things, and the companies start accepting bitcoin then it will take less time for all the people of the world to invest, trade and deal in bitcoin.
All other paper currencies will disappear and all the people will use just one digital currency and that will be only bitcoin, because bitcoin is the mainstream.
