Bitcoin (BTC) is the world's coolest 'currency' that nobody uses that much, yet its value has jumped 15 times in less than 12 months. Just for perspective, your ordinary bank fixed deposit will take 40 years to do so, stock market focussed mutual funds have taken about two decades while some stocks have done it in 10 years. Though Bitcoin has slipped to $14000 levels within 24 hours after hitting a high of $17900, its enthusiasts are convinced this is just a blip in the story.
