I have being casually observing bitcoins since 2011, but I have no skin the game. Personally I find the underlying technology very interesting. But as it is utilised presently, it is just a game of hot potatoes and it's going to end in tears. Although personally I think it's value will rise for longer and higher than people and even sceptics predict, possibly years before finally imploding. But it is a bubble, and it's not the only one there are many asset bubbles presently in many areas of global economy, for example housing, bitcoins is just one of many.
