McDonalds' will probably be doing this, in assistance with a government attempt to keep track of who has cryptocurrencies, for reasons that seem "good" to most people - but I don't trust them, or their crappy food. Anyone who trades cryptos for McDonalds' food, at this point in time, has got to be the biggest idiot, ever. I mean - both things will probably be sticking around for a long, long time - one is virtual coin, the other is virtual $#!t. :D
