Well, all assets started as unstable. But in reality there's no stable asset class. Even fiat is not stable. But the reason bitcoin is not stable is simply because it is a new asset class. People are still finding it's real value, it is called price discovery. Since it is very new, it is still finding it's stability. But overtime, maybe after all the coins were mined, it will become stable. When most people are using it. But such is the nature of bitcoin, it is still speculation. Even though it has use case -- transfer of value, it is still speculation currency. Who knows. Maybe hundred years from now, it will become the defacto currency of the world or maybe it will lose it's value and go down to zero. Who knows right? But in the next coming halvings, I think it will reach it's relative stability. As of now, if that is what you are looking for. You're not in luck. Better yet, play with it's instability as long as you can, you can earn from the spread.
