you already understand the concept of Volatility, where Volatility reflects the level of risk when using one instrument or another, the higher this indicator, the greater the range of changes in the exchange rate within a certain period of time.
however, I tried to think about it, maybe this could be the decisive factor bitcoin will be stable:
1. public awareness about the function of bitcoin as currency rather than as a growing digital asset.
2. the need for the consensus of society with the market, to make decisions.
3. technology balancer to the miners so that miners do not lose.
4. each country can make a deal through the central bank to determine the price of bitcoin in the market.
