LONDON, Oct 31 (Reuters) - Bitcoin jumped to an all-time high above $6,300 on Tuesday, after the world's largest futures market operator CME Group said it would launch a regulated trading venue for cryptocurrencies in the fourth quarter of 2017.
The new futures contracts will be settled in cash, based on the CME 'CF Bitcoin Reference Rate', a once-a-day reference rate of the U.S. dollar price of bitcoin, the company said.
The price of bitcoin jumped to as high as $6338.60 according to trade website Coindesk's price index, which aggregates the prices quoted across several exchanges. That was up from around $6,215 before the news.
On the Luxembourg-based Bitstamp exchange, bitcoin jumped to as high as $6,351, up almost 4 percent on the day.
Bitcoin has surged in value by around 555 percent so far this year. (Reporting by Jemima Kelly; Editing by John Geddie)
