From two pizzas to a £17m mansion: Bitcoin's soaring value creating bubble fears?

The house that money can't buy...

A mansion in Notting Hill, London has recently been put on the market for sale. But it isn't coming cheap. The owners are apparently only accepting bids which are made in Bitcoin. The asking price is a staggering £17 million pounds! Or should I say £17 million worth of Bitcoin, approximately 5,000 of them to be exact!

In 2010, someone purchased two pizzas with 10,000 Bitcoin. At 5,000 bitcoin per pizza, that amount can buy you an entire mansion in one of the most expensive locations in the United Kingdom. An extraordinary rise in value. Is this a bubble? Could the great digital currency be heading down the drain?
