It's been a particularly interesting week for Bitcoin, the popular virtual currency that is stateless and anonymous, and thus nearly perfect for all sorts of "commerce" on the Internet that people don't want to run through a PayPal account.
First, even by the standards in Bitcoin trading it was a wild ride this past week, with one Bitcoin trading in a range of $340 to $1,240 just this last week. Those prone to airsickness probably shouldn't hold any Bitcoin.
Then, the Norwegian government became just the latest to declare that a Bitcoin isn't money.
The European Banking Authority ended the week by issuing what was effectively a blanket warning, citing the wild fluctuations in price, the danger that the so-called digital wallet could get hacked and the complete absence of legal protections for users.
It's not even clear that if an owner gets all of his Bitcoins stolen that there would be any way to show that a crime had been committed.
Fidelity Investments, the big mutual fund company, also took steps this week to block investments out of clients' IRAs into a Bitcoin investment trust.
For Bitcoin enthusiasts, these are the pronouncements of people who just don't understand. The appeal of Bitcoin is that it's stateless, anonymous, and beyond the reach of mutual fund managers, regulators and central bankers, who back in 2008 didn't impress anyone with their competence, anyway.
So the Bitcoin craze continues, with even a firm in Sweden opening this past week what it called the world's first Bitcoin automated teller machine.
