Kate Jaspon made the remarks earlier this month while pointing out the uncertainty and the difficulty of predicting future events.
Ms Jaspon said: “Whether you support him or not, I don’t think anyone in this room would have guessed that Donald Trump would have been the 45th President of the United States.
“I know I didn’t.
“And then from a digital currency perspective, I mean, Bitcoin, years ago we had conversations about whether Bitcoin would be a real thing and here it is trading at all-time highs.”
In the past month 24 companies have referenced the cryptocurrency in their analyst day conference calls, according to an analysis of FactSet data.
The fact that major companies are discussing Bitcoin highlights the degree to which the cryptocurrency has become a massive point of economic interest.
Howard Schultz, the Executive Chairman of Starbucks, discussed Bitcoin in a call last month.
He said: “I don’t believe that bitcoin is going to be a currency today or in the future.”
However, he stressed that blockchain technology could become a central technology to businesses over a 20-year timespan.
He added: “I am not bringing this up because Starbucks is announcing that we are forming a digital currency or we’re investing in this.
“I am bringing this up because as we think about the future of our company and the future of consumer behaviour, I personally believe that there is going to be one or a few legitimate, trusted digital currencies off of the blockchain technology.
“I believe that we are heading into a new age in which blockchain technology is going to provide a significant level of a digital currency that is going to have a consumer application.
“And I believe that Starbucks is in a unique position to take advantage of that.”
Mr Schultz expressed his firmly held belief that exploring technologies such as bitcoin reflected what he saw as a necessary initiative for Starbucks to stay competitive.
Economics professor Panos Mourdoukoutas has argued both Starbucks and Dunkin’ Donuts have been talking about Bitcoin because accepting it as a form of payment for their products will create a buzz for both companies among young customers who are fans of the digital currency.
For the moment, neither Starbucks nor Dunkin’ Donuts accepts bitcoin payments.
At present, the value of one Bitcoin equals that of approximately £7,375.
