I don't think so, We can't even use credit/debit card as a payment in MaDonald(China area),let alone use Bitcoin.
What do you mean "let alone". You make it sound if accepting Bitcoin is even
harder than accepting credit / debit cards. Well, quite the opposite, actually. Of all payment methods (including cash), Bitcoin is the
easiest, cheapest and safest to accept.
Also, Mcdonald might suffer losses for the Bitcoin price volatility.
Ah geez, not that shit again
No, McDonald (or any merchant) doesn't care the slightest bit about price volatility. They use a payment provider (for free) and they get paid in Euros or Dollars. Zero risk involved for them.
