Re: Where's the value?
The currencies thrust onto people are no different - just check it out - we've been duped into thinking that they are backed by Gold. As I understand it only the Swiss Franc and now more recently the Renminbi are backed by Gold.
Solaris_fan,
You don't understand it then. No currencies are fully backed by gold. The Gold Standard was a horrible farce that failed miserably and led to the 1930s depression. The next attempt at it, with Bretton Woods didn't work properly either. The Euro is causing a depression, just like the Gold Standard, but without the shiny bars.
To many of the other posters, major international currencies aren't backed by commodities. But they are backed by the countries that use them. The reason the Euro is in serious trouble is that people are beginning to suspect that when the going gets tough, countries will leave. They are aiding this feeling, but always nearly doing enough to bail themselves out, but never quite doing the job properly, and always doing it too late. Eventually the brinkmanship will fail, and the Euro will most likely fall over.
If however you've only got the one currency, and you've got national assets (not least a population and modern economy), plus a government and a tradition of a rule of law, then your currency is backed by something. Sure our government could inflate the Pound to Zimbabwe like levels, but there's 63 million of us who are stuck with it, so they're unlikely to.
Also, history helps here. Britain has hundreds of years of not defaulting on its government debt and not destroying its own economy. Even when debt hit 200% of GDP a couple of times from fighting world wars. Britain invented national debt 250 years ago, and has always paid up. The US also have a long history of abiding by contract law, and not defaulting.
The Euro has a much shorter history. If today's news about the horrifically fucked up Cyprus bail-out causes it to leave then the Euro will be in a bad state as a fiat currency. Where no-one seriously believes the voters and governments will honour their commitments.
Bitcoin has even less backing. There is no government to stand behind it. Its short history is of hacking, scams, collapses in confidence, bizarre screw-ups where people have to roll back software updates or exchange trading to correct for errors, and randomness. Any faith in that system would be absurd. And there's no government or workforce to stand behind it.
