If the world uses a single currency, will the economy be more stable?
This is a very interesting question. The sovereign nations issue their own currencies and are taken for granted by many people, but few consider whether this is the economically optimal option.
it would be great, but it's not going to happen. look at people.. look at political situation now.. it seems that we will never be able to live in peace, and this disappoints me.. so, no.. the governments of different countries will never come to single currency
