If the price of Bitcoin was not volatile, then Bitcoin would not have attracted investors. So when Bitcoin was created, these things were pre-planned so that it could attract the attention of investors and create a hype worldwide. And Bitcoin has been able to do this, which is why Bitcoin is now a digital currency discussed in the whole world that everyone trusts and invests in large amounts. Bitcoin's volatility can be called its religion. Not only Bitcoin, but every coin in the crypto market, except for a few stable coins, is volatile and this is why you yourself are thinking about Bitcoin and are interested in investing here.
I agree that if Bitcoin weren't so volatile and didn't generate such huge returns, it wouldn't attract investors and wouldn't have reached its current position. But I don't think these things were planned before Bitcoin was created. Satoshi created Bitcoin as a peer-to-peer currency, he had no intention of turning it into a speculative asset. The volatility of Bitcoin is due to us, the early investors, instead of using Bitcoin for Satoshi's original purpose, we turned it into a speculative asset.
Bitcoin's volatility cannot be called a religion, because as Bitcoin matures over time, its volatility will decrease. It won't be as stable as stablecoins, but it will be as less volatile as gold at some point.
