Nowadays, the subject of world currencies seems to be an often-discussed topic. There are discussions about the descending dominance of the United States of America and dollar, an increasing role of Chinese renminbi, and the troubles of the Eurozone and euro. In 2014, China became the biggest economy in the world.The fact that USA, which was dominating the world economy for 142 years, was surpassed is considered as the end of its dominance and the dominance of dollar.
