I think it depends on the purpose of how you are going to use Bitcoin and your strategy. If you want to pay with Bitcoin, its volatility is a real disaster for you. But if you are a trader, you can earn on its constant fluctuations. If you are a long-term investor, you just don't have to worry about volatility, as your target is holding for several year.
The bitcoin volatility is not that bad to be called a "disaster" as you put it. It is annoying at best. For example if you look at the past 60 days we only had 2 big rises and 2 big falls that are bigger than 10% and covered about 5 days, the rest of the time meaning most of the remaining 55 days market was moderately calm. For example in the past 10 days the biggest thing we had was a 2.5% drop and a 4% rise!
This is just the most recent case, in the first 4 months of 2019 (~120 days) price was a lot more stable and for much longer.
