Yes I agree. Bitcoin prices will continue to be volatile and fluctuations will still exist. And this is indeed one of the attractions of Bitcoin itself.
But on the other hand, if mass adoption of Bitcoin is truly successful and develops very rapidly throughout the world, then it does not rule out the possibility that its volatility will decrease. In this case, decrease yes, not become non-existent or even stable. So there is still volatility but it is decreasing and not as high as it is now.
True. Bitcoin will be always volatile, there is no way to make it be stable. The demand for Bitcoin is natural, no institution determines it. And we know that Bitcoin is decentralized, it is no control from any one. So, I don't see a chance that the price will be stable in the future.
Bitcoin adoption will develop, we have seen some good progress on the adoption. Even if Bitcoin will function as the currency in the future. I think it won't make the volatility be disappeared. It will always exist although it become lower volatile.
