Bitcoin is in the news again thanks to another scare. I think the obsession stems from the fact that it is a currency so people intrinsically understand it over other types of digital technology with less analogies in everyday life.
I haven’t bought any Bitcoin or similar. My take is that individual digital crypto-currencies will come and go over the next few years while the legacy technologies (pounds, dollars, euros etc) persist. Eventually though, and it will take a while, there will be a single global currency outside the control of Governments or individual institutions. The technology is out of the box — but I wouldn’t want to bet yet on which of the many thousands that will be created will win out.
