Lest anyone think they live strictly in the domain of underground computer geeks, no less a source than Art Cashin, the well-respected market veteran and director of trading floor services at UBS, addressed the craze in his morning note to clients.
"It is rare that we get to see a bubble-like phenomenon trade tick for tick in real time. Usually it's kind of regional aggregate pricing like real estate reports," Cashin said. "But, all that may be changing—before our very eyes—quite literally. The bubble du jour may be something called a 'bitcoin.'"

There are several events that could be tied to the recent surge in Bitcoin trading.
Financial media outlets have glommed onto the trade; the price surged 13.5 percent a week ago, coinciding with a CNBC.com report on the phenomenon.
At the same time, the trade got a huge boost when the Financial Crimes Enforcement Network on March 18, without mentioning Bitcoin specifically, said it will not prosecute those issuing what it deemed "virtual currencies."
Also, Western Union recently said it will begin experimenting with digital currencies for customer convenience.
Throw into the mix geopolitical turmoil, such as the tax imposed on private depositors in Cyprus to stave off the nation's banking crisis, and the stage has been set for a meteoric Bitcoin surge.

"It got traction because it's decentralized, it's not subject to government meddling, it's considered safe and there's limited supply. So that drives value in kind of a commodity-type perception," Safahi said. "We now have a whole new generation of geeks who are willing to accept open-source as reliable."
Whether the Bitcoin craze ever spreads beyond those "geeks" is dependent on several factors.
One of the primary issues is security—critics worry that a clever hacker could plow into a Bitcoin system and pilfer accounts with aplomb. Some were concerned that volatile Wednesday trading, which saw a range from $147 at the high to $107.08 at the low, suggested the system is subject to a "Hack Crash" similar to the stock market's 2010 "Flash Crash" that sent major averages plummeting in a matter of minutes.

"It's impossible to ignore, because everybody is tweeting me about it. It's on everybody's radar displays," said Boris Schlossberg, managing director at BK Asset Management. "As far as a viable currency, it's a fantasy in most people's eyes, but it's definitely emblematic that there's a huge amount of anxiety among the investment class."
Schlossberg figured the enthusiasm w`ill last as long as it takes for the government to decide Bitcoin use has become too widespread not to be regulated.
"At the end of the day if the government decides to regulate it one way or the other you may wind up with just a bunch of code in your hands and nothing else," he said. "It doesn't really have any value other than it's socially acceptable."
