Bitcoin: this is what a bubble looks like March 28, 2013

That’s the market capitalisation of Bitcoin, an innovative fiat currency which relies on some fancy cryptography to create a perfectly decentralised and unhackable store of value. The graph shows the total value of all bitcoins in circulation — and it’s currently peaking at a little over half a billion dollars.

In a sense, Bitcoins are the ultimate fiat currency. There is absolutely nothing valuable about them except the extent to which others are prepared to take them as payment for goods and services. The willingness relies on a certain level of trust that the currency will stay a useful store of value, measure of exchange and unit of account in the near future; but whereas normal currencies derive the trust from the fact that they are backed up by respectable governments and independent central banks, Bitcoin derives it from a complex, and essentially permanent, set of rules which issue new bit coins at a steadily declining rate until the early 22nd century, when the total quantity of bitcoins in circulation will be fixed forever.
