New Delhi, Nov 28 (ANI): Cryptocurrency bitcoin has soared record high and is just a few percent away from the 10,000 dollar mark. Bitcoin's seemingly unstoppable ascent continues, gaining more than a fifth in value over the past three days alone. The digital currency has seen an eye-watering tenfold increase in its value since the start of the year. Bitcoin surged 4.5 percent on Monday to trade at $9,687 on the Luxembourg-based Bitstamp exchange. Its price has been helped in recent months by the announcement that the world's biggest derivatives exchange operator CME Group will start offering bitcoin futures.
