No, it will never be able to bring world peace.
Basically it is a currency and currency don't make world peaceful, the rich get richer and poor get poorer and that increases the differences between poor and rich people and there comes hatred between them and world peace get destroyed.
Yes, it would create an individual differences within the people, and surely it won't contribute anything towards world peace, I don't understand what is the relation or connection between bitcoins and world peace, and it would never contribute towards economy of the country as it is decentralised and no one has control over it.
