No, this isn't some strange unrelated "burger king". This is the real one, in Russia.
"The main difficulty is tax issues, rather than integration ... You'll be able to pay with cryptocurrency in the future", - said General Director of "Burger King Russia" Dmitry Honey.
On the 10th of August, Burger King Russia will be announcing the winner of their request for tender - after reaching out for companies to provide them a good Bitcoin payment solution in-store and possibly online.
Maybe they'll get tired of the long confirmation times, and someone will tell them about STEEM. Fast food isn't so fast when you wait 1 hour for 1 confirmation on Bitcoin.
It's unknown whether they will expand Bitcoin payments to other parts of the world, Burger King is a large multi-national corporation, and many of the regional companies operate rather autonomously (have you seen the strange food items they sell in Japan for example? Image above of the dark burgers they sell in Japan).
It could be that this stays in Russia, it could be that Bitcoin is a massive flop and they just drop it, maybe they'll try some other cryptocurrencies, or maybe it'll be so successful they start to roll it out across the world.
