Liberland Chooses Bitcoin as National CurrencyLiberland is the newest European country. Liberland came into existence due to a border dispute between Croatia and Serbia. This area along the west bank of the Danube river is not claimed by Croatia, Serbia or any other country. It was therefore terra nullius, a no man’s land, until Vít Jedlička seized the opportunity and on 13 April 2015 formed a new state in this territory. Vit Jedlicka, settled the country on this territory and has established Bitcoin as the national currency.
