They are the same no matter what currency is that and maybe its possibe that price could be higher in the current price if you wanted to buy in a local exchange site(of course using your own local currency)but lower than the current price when your going to sell.
that's right its always depend from what currency are we using and which currency we wanted to exchange our btc, i think usd is the main basis of its current price but going to our local exchanges we will need to stay on their current price as well.
