Bitcoin prices have shot past $900, the latest move in a week of dramatic market increases.

The digital currency’s price peaked at $911.99, according to data from the CoinDesk USD Bitcoin Price Index (BPI). Prices haven’t exceeded the $900 level since mid-January 2014, BPI data shows.

At press time, the price is hovering around an average of $902.92.

The development comes only two days after markets worldwide crossed the $800 mark, followed by additional action yesterday that saw the price exceed $870 before dipping.

The rapidly climbing price has sparked headlines across major news outlets, culminating a year ofdramatic market movements that have followed events like the UK vote to exit the European Union and the election of Republican Donald Trump to the US presidency.
