With the way bitcoin is being speculated on right now, it is not impossible for bitcoin's value to get to $0.00. People are hardly rational and should an attack on the confidence of major bitcoin holders occur, we may very well see bitcoin being shorted to such a degree that it's value would go nil. But though such a scenario is a possibility, I believe that there are a lot of wealthy individuals who are already too invested in bitcoin to allow such a thing to happen. Their ultimate agenda may be to use bitcoin as a standard on which other cryptocurrencies will be referenced to, similar to how the dollar is right now and the UK pound before that. Thus they will use their resources to protect bitcoin and keep it stable.
