Bitcoin, the digital coin with a questionable past, is gaining ground as a legitimate currency, trading at $32 a share last week.
It poses a tangible threat to centralised banking and the guardians of fiat money. Bitcoin won’t knock off the dollar any time soon; the euro can sleep easy. But it is clearly a force to be reckoned with. Bitcoin has become the world’s best performing currency, with its value spiking 130% just this year.
