Megan McArdle - Megan McArdle is a senior editor for The Atlantic who writes about business and economics. She has worked at three start-ups, a consulting firm, an investment bank, a disaster recovery firm at Ground Zero, and The Economist. More

Megan was born and raised on the Upper West Side of Manhattan, and yes, she does enjoy her lattes, as well as the occasional extra-dry skim-milk cappuccino. Her checkered work history includes three start-ups, four years as a technology project manager for a boutique consulting firm, a summer as an associate at an investment bank, and a year spent as sort of an executive copy girl for one of the disaster-recovery firms at Ground Zero … all before the age of 30.

While working at Ground Zero, Megan started Live From the WTC, a blog focused on economics, business, and cooking. She may or may not have been the first major economics blogger, depending on whether we are allowed to throw outlying variables such as Brad Delong out of the set. From there it was but a few steps down the slippery slope to freelance journalism. She has worked in various capacities for The Economist, where she wrote about economics and oversaw the founding of Free Exchange, the magazine's economics blog. She has also maintained her own blog, Asymmetrical Information, which moved to The Atlantic, along with its owner, in August 2007.

Megan holds a bachelor's degree in English literature from the University of Pennsylvania and an M.B.A. from the University of Chicago. After a lifetime as a New Yorker, she now resides in northwest Washington, D.C., where she is still trying to figure out what one does with an apartment larger than 400 square feet.

After the Crash, What's Next for Bitcoin?

It's been a wild ride for Bitcoin, the decentralized virtual currency "mined" across the internet.

Over the last few weeks the currency's value rose 30-fold to more than $30 before falling back to $10 and rising again to $20 late last week. But Bitcoin prices fell to pennies this weekend following a security breach that allowed as much as $8.75M worth of Bitcoins (at pre-crash prices) to be (temporarily?) stolen.

This follows last week's news that 25,000 Bitcoins were illegally transferred from accounts on the currency's largest exchange "allinvain's" computer, a heist then valued at nearly $500,000.

Following Sunday's mess, trading has been suspended and Mt.Gox is currently down as is competitor TradeHill (where prices closed at $13). Both sites allowed users to trade Bitcoins to and from U.S. dollars and Mt. Gox accounted for nearly 90 percent of Bitcoin's average daily trading volume.

This spate of bad news and volatility leaves many wondering if this is the beginning of the end for the Bitcoin movement. Dedicated geeks and technologist are working to improve the security surrounding exchanges while encouraging more online merchants to trade in Bitcoins. But encrypted .dat files and randomized algorithms may be too much for a population whose most popular password is 123456. Can it ever have both sufficient security and mainstream users?

If you're looking to learn more about Bitcoin read The Atlantic Wire's overview, This Bitcoin Business Is Entirely Out of Hand, check out this helpful FAQ from WeUseCoins, dig a little deeper with The Economist's piece, Bits and Bob, and when you have a good sense of things read Eli Dourado on bootstrapping Bitcoin and Tim Lee's skeptical take.

2:30 ET Update:  Bitcoin is trading again on Tradehill. You can see live trading data at: https://www.tradehill.com/MarketData/
