From the moment I understood Bitcoin, I knew all the talk of it going to zero was just BS because as long as there is a demand for Bitcoin, it will never get to zero. If there were no demand, it wouldn't be climbing as much.
Funny enough even when bitcoin is dipping there is still demand for bitcoin because it is at that time that people who understand bitcoin buy or else there will be no phrase like "buy the dip".

I do not know what the future holds, but a future with no demand for Bitcoin will mean something very unexpected and unexplainable happens like a world war or something.
