“What do you think about bitcoin?”
Over the past few months, I’ve gotten this question more than any other. In 2017, bitcoin, the world’s first cryptocurrency, rose by almost 1,200%, prompting excitement and bafflement.
My answer: I’m enthusiastic about the blockchain technology that makes bitcoin possible. In fact, Vanguard is using such technology.
As for bitcoin the currency?
I see a decent probability that its price goes to zero.
