It is volatile and that scares some people off. It is currently on the rise again, but personally I am not interested in high risk outlets. I really don't even care about being rich. All I really crave in life is a little security and certainty. I am not particularly greedy. I look at huge businessmen here arrested for corruption and just think 'Why are you doing that? You have more than you need and beyond'. I am materialistic in that I don't want to be homeless, but not so much that I crave opulence or anything excessive. I always considered Bitcoin and it would do not harm to invest a bit, but it would be for sport more than anything else. Just another egg in another basket.
