 It's Friday, February 28th, 2014. I'm Adrienne Jeffries and I invite you to join my new bagel exchange, Mount Gawks. This is 90 seconds on the verge. Mount Gawks has filed for bankruptcy protection, claiming $64 million in liabilities. The embattled Bitcoin exchange says it has lost close to 850,000 Bitcoins, which is worth about $500 million. 750,000 of those belong to customers and 100,000 were company assets. Mount Gawks is currently under investigation by authorities in both the US and Japan, and as for the digital currency itself, it's lost about a third of its value since February 1st. Microsoft is experimenting with a free version of Windows 8.1. The company is building a, quote, Windows 8.1 with Bing, which will bundle key Microsoft apps and services into a free or at least low-cost upgrade for Windows 7 users. The experiment is part of a number of initiatives designed to push and monetize Microsoft's cloud services, as well as get more people using the latest version of Windows. Microsoft recently announced a major Windows 8.1 Spring update, with additional details to come at its annual Build conference in early April. And finally, believe it or not, there's a Minecraft movie in the works. Warner Bros. has acquired rights to make a feature film based on the wildly successful sandbox title. It's actually a perfect fit for the studio, which released the Lego movie earlier this month. That film has grossed nearly $300 million worldwide. Financial details weren't disclosed, but estimates have been in the range of six diamond blocks and a dozen or so golden carrots. That's it for today's top stories. Coming up tomorrow? Saturday!
