If Bitcoin becomes the store of value for the majority of the people unbanked, it could replace gold as the preferred medium for storing wealth.
To replace gold bitcoin must make the price stable enough because compared to gold bitcoin is too far to make it stable. And one more thing that without the volatility of bitcoin, bitcoin will lose their attractive to people because bitcoin will no longer as a trading but a pure investment. So it must be considered well enough
bitcoin is fairly stable recently, if we can maintain this climbing, we can have both, stability and a good price
also volatility it's bad only when bitcoin falls, not when it's rise for evident reasons, this is not true for merchants, but it is true for holders
