I also believe that it's possible that bitcoin loses ist value. It may go down to any Price again. There is just nothing that makes btc a safe heaven.
Anything can happen in the future. But I think there are slightly less chances of this thing to happen. The way Bitcoin is gaining the attention of so many people sitting in the market and the way people are investing in Bitcoin, I think this is a proof of this thing that Bitcoin holds a very bright future.
As much as we have hopes and there is still a great support for bitcoin, I do not see how bitcoin can ever lose its value completely.
Yet, I do not see how that can ever be, with what is involved in bitcoin already, this is the last topic we should even be discussing. What we should be discussing now is how we can easily survive the huge adoption once bitcoin starts hitting the mainstream.
