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.
Almost certainly not a
disaster as they put it, though I would say it's far from ideal for those that use Bitcoin as a currency rather than an investment. Although, those do seem to be rather thin. Most users here, and most people I know invested in Bitcoin are doing it to eventually cash out back into fiat.
Ideally, it would be nice to see the volatility be below 1% over a extended period of time, at least from a user point of view. The investors probably wouldn't be happy with that, and undoubtedly would start posting about Bitcoin being dead.
It's the fees, and the volatility which is the stumbling block for being able to use Bitcoin for every day items, and needs I would say. Though, progression is definitely being made towards bettering the fees, and think it's a common thought process that the volatility will get better in time.
