At the CNBC global CFO conference, 97 CFO were asked about their views on bitcoin. 27.9% of them think the encrypted currency is trueBut in a bubble state~

You do know that 27.9% is a minority??
What were the other options and what percentage of the vote did they get? It all depends on this. Without this information the 27% measure is useless.
Yes 27% is minority and how about the other 73%?? In the world, people can have different opinion so maybe the other 73% said that bitcoin is best way for investment and next currency in the world.
They can say what they want, they are just envy to what is currently happening to Bitcoin. And this has been a no surprise for the most of us here in the community, since every year Bitcoin went into the same path as the last year so, the process of increasing in value is quite the same but higher. Its not a bubble really, its a hike or what we called pump. Its not just for a show and then going to be dumped later, its just that, there is also this time of the year where many people hold Bitcoin as much as they want, making it having a little dump and wait for the right price to make a good profit for themselves. Just like what happened now.
