Felix Salmon on “The Bitcoin Bubble and the Future of Currency” a primer on the crypto-currency

Each time the value of a bitcoin hits a new high or a new milestone, there’s more press coverage of the phenomenon, drawing new people in, and sending the value of bitcoins even higher. Indeed, if you chart the value of bitcoins against the number of times that they’re being talked about on Twitter, you’ll see a very strong correlation. And because of the Cyprus connection, mainstream publications have a handy real-world news hook, now, with which to explain the bitcoin phenomenon.

This is actually a serious problem, if you’re trying to put together a currency, rather than a vehicle for financial speculation. If the currency of a country ever fluctuated as much as bitcoins did, it would never be taken seriously as a medium of exchange: how are you meant to do business in a place where an item costing one unit of currency is worth $10 one day and $20 the next? Currencies need a modicum of stability; indeed, one of the main selling points of bitcoin was that it couldn’t be destabilized by government institutions. But that comes as scant comfort to people watching the value of a bitcoin behave like some kind of demented internet stock during the dot-com bubble.

And just like demented internet stocks, bitcoins have seen busts as well as bubbles: in the second half of 2011, for instance, the value of bitcoins retreated from their peak around $30 each to a low point closer to $3. (Today, they’re trading above $140.)

In reality, then, bitcoin doesn’t really behave like a currency at all. In terms of its market value, it looks much more like a highly-volatile commodity. That’s by design: bitcoins were created to be the most fungible commodity the world had ever seen – to the point at which they would effectively erase the distinction between a commodity and a currency.

But is that a good idea?


 Good question. More in the longish essay by Felix Salmon at The Medium.
