Stable price is only good for the crypto users who use Bitcoin for direct spending and payments but for those who considered Bitcoin as good for investments then they will always look for more that Bitcoin will become all time high again.
I believe, but isn't it the purpose why bitcoin was created?
Being an investment is just a second consideration because without much people using the system, the adoption will not grow and that would also reflect on the value of bitcoin.
More demand means more valuable, that's what I'm seeing.
