Still not sure what to do with all your bitcoins? Dell has a solution. The computer-maker is now accepting the cryptocurrency as payment, with company founder and CEO Michael Dell announcing the news himself on Twitter. To promote the news, which Dell calls a pilot program, the company is also offering a 10 percent discount on any Alienware products you buy through its site using bitcoin. The company is working closely with Coinbase, a digital wallet for storing the online currency, and says it set the entire payment system up in just two weeks. It’s a big step for bitcoin, which has grown increasingly popular but still can’t be used for many mainstream purchases. Dell is also an obvious choice, since most bitcoin collectors are probably computer fans as well. A few other companies, including Overstock.com, already accept the new currency, but according to Michael Dell this is biggest to date.
