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.
It is really going to be a good sign, but as it is, I doubt if going mainstream is even possible. We still have some pretty high tx fees, transaction time is a little too low and etc. However, there are some other cryptos that I feel will be good for usage and that may have to be what we will end up having eventually.
Hardly will you really see people making use of paper currencies these days with the cashless age, so the use of bitcoin or crypto will even make it more extinct.
