Saw this on the interwebs

My 2 sats... I paid mine with my Bitcoin card and I couldn't care less if the merchant receives euro, dollar, yen or any other "local currency". It's just a forex aka "foreign exchange"

You can pay almost everywhere with Bitcoin and it doesn't matter which currency the merchant receives. Same as it doesn't matter when you travel from the US to the UK, swipe your card, pay in USD and the merchant receives GBP.
