How deep does this Bitcoin rabbit hole go? The virtual currency is looking less and less like videogame money and more and more like real world money. The BTC exchange Mt. Gox shut down over the weekend after a miniature version of Wall Street’s famous “flash crash,” in which high-frequency trading caused the Dow to drop 600 points. The BTC crash was caused by a massive sell-off that sent its value spiraling down to $.01 and then, somehow, into the negative, within minutes. |
