You might say that crypto currencies have been on a rollercoaster ride over recent months but only if the rollercoaster you were thinking about had a peculiarly and uniquely downward trajectory.
Less than six months ago the value of the virtual currencies that have turned the heads of financial wizards, big business, criminals and — increasingly — small scale and mostly young investors all over the word, was put at an astonishing three trillion dollars. That’s a three with 12 zeros.
Today, the value of the world’s cryptocurrency market is less than one trillion dollars and the smart money is not betting on a recovery any time soon.
But what is behind the collapse and is it just a dip in a volatile virtual currency or is digital money in a death spiral?

He talks to In The News about the rise and fall, and fall and fall, of virtual money and pores over the runes - or should that be ruins - to see what might come next.
