Guys... Sorry if I'm too noob to this thing, but...
There's already a GLOBAL coin for everyone, called bitcoin.
There's another GLOBAL one which is different in its algorhythm, called litecoin.

These are GLOBAL coins. Everyone in the world can use them.
So why do you try to LIMIT a coin to a country AT ALL? It's like you wanted to regulate it, just like governments try to do. Even your people can't understand not to sell them just after receiving them.
What's the use of creating all kinds of more global coins at all? They're all targets for speculators, nothing more.

We already have the solution for the whole world's problem, and it's called bitcoin. (and maybe litecoin)
