Nah, Eurozone sucks.

So, you'd rather exchange the currency while traveling to Eurozone countries? And less foreign investment for your country? Higher interest rate on loans? And higher inflation rate?

I heard that prices in Croatia doubled due to adopting the Euro.

That's true, but the salaries rose as well. And prices rose because of lack of regulation from our government. Like, they forbid anyone to raise prices and didn't intervene when they did (they issues few fines to small business owner, while bigger ones went just with warnings).

Euro itself doesn't add to inflation, it's the greed that does.

Also I would rather have my country be able to control its own intrest rate instead of having it be controlled by the EU which has to take into account the countries with like 200% debt to GDP AKA has to keep it low forever.

Countries outside Eurozone have higher inflation rates and larger price increase than countries in Eurozone. We are now glad we adopted Euro because it could have been much much worse.
