The internet likes to tell the story of a programmer who bought two pizzas for 10,000 bitcoins for the first time in 2010. Today, the pizzas would be worth nearly $40 million. In this year alone, the price of a bitcoin has increased by more than 300 percent and has already scratched the $5,000 mark. Japan is often cited as the reason for the rally. There, Bitcoin was declared official means of payment alongside the yen at the beginning of April. According to Australian media, Sydney is also discussing it. Political uncertainties, currency crises, increasing interest from institutional investors and the general hope of price gains are also fueling the price.
