Bitcoin could very well be the investing story of 2017, with its meteoric rise in price (up more than 1,100 percent year-over-year, according to Coinbase). Comments from billionaires and business barons who have called it a bubble — including Jamie Dimon, Jack Bogle, Warren Buffett and Mark Cuban — haven't deterred believers. And you can add to the doubters' list another group of big-name market skeptics. More than one quarter of respondents (27 percent) taking the recent CNBC Global CFO Council survey see bitcoin as a fraud, while another 27 percent said it is a "real" asset, but in a bubble. Only 14 percent say it is "real and still going higher" in value.

More than half of all respondents have a pessimistic view of bitcoin. A third of respondents admitted they do not know enough about bitcoin to have an opinion. The CNBC Global CFO Council represents some of the largest public and private companies in the world, collectively managing more than $4 trillion in market capitalization across a wide variety of sectors.

On Wednesday the cyrptocurrency hit an all-time high of more than $11,000, before plunging 20 percent. On Thursday the trade stabilized and bitcoin was trading at $9,487.82. U.S.-based members of the CNBC Global CFO Council are most bearish on bitcoin, with just under 35 percent having a favorable view, while EMEA-based CFO Council members are the most bullish, with 57 percent of respondents maintaining a favorable view. "It is something we are curious about, we're very very open to, but we haven't found a way to really integrate it into our business," Karim Hajjar, CFO for the Belgian chemical company Solvay, told CNBC in November.
