As long as there is a currency that lets me buy a burger, i dont care what it is. lol.
Realisticly speaking? Most people won't. Because why should they care? They gat their wage from a job, spend it on rent, power, gas and food. What sign is behind it hardly matters - if euro, dollar, or rubel. 
Is what it is. Neat, interesting, but ultimatively, "eh, moving on."
