If you ask established authority figures within the financial system – for example Deutsche Bank chief strategist Ulrich Stephan – “should we invest in Bitcoin?” then the answer is generally an emphatic “no”. It’s high volatility, lack of obvious use other than as a vehicle for investment, and the bubble-like behaviour of its value are usually cited as flashing red “danger” signs. And logically, one would expect these people to know what they are talking about.
