Bitcoin, the oldest and most famous digital currency, rose above $80,000 at the start of the week. This is the highest level the cryptocurrency has ever reached. What's going on?

Trump is pushing Bitcoin higher

Many observers say the key factor is the election of Donald Trump as the new US president - that's why Bitcoin has been steadily growing since November 4. "Trump has said that he will become a crypto president and will lead the US to a leading position in this area," says Jonas Groß, head of the Digital Euro Association (DEA), an organization that promotes electronic payment systems. Until now, such promises have only been made by presidents of small countries such as El Salvador. So it's no surprise that those involved in cryptocurrencies are simply jubilant now.$BTC
