Can you buy anything real with Bitcoin? On the streets of Bristol, it proves a hard sell

The digital currency can now be bought at ATMs around the country

My journey into the dark economy starts much as expected: in front of a computer screen, late at night. It ends somewhere quite unexpected, in a humdrum setting a world away from the stereotype of modernity, equality and sticking it to the man promised by digital currencies such as Bitcoin: it ends in a used DVD store, my purchase refused.

The dark economy is moving into the light. In a few scattered places, 40 or so in London, one in Manchester, another in Birmingham, Bitcoin ATM machines have appeared, issuing the cryptocurrency from an unlikely array of convenience stores, vaping outlets and barbershops. Does this mean that the virtual has become real? Can anyone join the Bitcoin challenge? Can you buy stuff with Bitcoin? And what the heck is a cryptocurrency anyway?
