Single Currency

I have wondered many times what the meaning of the existence of multiple currencies? I think a single currency could have a lot of benefits like reducing the cost of economic transactions and making the pricing of good and services more effective. Also, it would end the currency speculation and the effects of it and would boost the economic activity among various countries.

71% of respondents in the poll would like to have a single currency.

I would like to have a single language before I had a single currency. The benefits to the world economy would be even larger than if you only had a single currency. More trade, more travel, more understanding, more cooperation. So if I had to choose between a single currency and a single language, I'd rather have a single language. A single language would inevitably lead to a single currency as the world would become one in terms of how people think. A single currency without a single language means the world can trade better than if it had multiple currencies but it doesn't become one. So what I want to say is that under a single currency the world improves, under a single language the world becomes one. Within this context, which would You rather have?
