Even "Bitcoin stability" has become news now? I very much doubt it's the longest stretch of stability in its history. Didn't it stay at $13-$14 for like a year? And I think even last year it stayed more at around $140 than it has at $800. If we look at their own chart that's only since September we can see it's actually been stable for longer in the September-October period.
I think it's just the BI guys who are obviously invested in Bitcoin, and are eagerly awaiting for the price to explode again, so it staying stable for a whole month seems like forever to them.
