Volatility will go lower with higher price (bigger market). Look at the volaitlity back to 2010, 2013 and today. Today a 20% change is 800~1000USD, which is already a lot, at that time a 50% correction can be seen. So when the price will reach 50k USD, I think the volatility will be much smaller.
I would agree if it was guaranteed that price would go up to $50.000
(At least, the probability of lower volatility in these price regions is much higher).But that is still very far away from now. It is well possible that in its current incarnation (with still very high volatility) the necessary adoption of Bitcoin by the average Joe (or at least the "big capital") will never happen. We however may be lucky and one or two bubbles later we see those prices combined with high liquidity and everything is fine. But my stance is that we should find ways to control volatility a bit more, so the way up will be less bumpy and more straightforward.
