Let me just go on a short Bitcoin volatile history,but you can still carry out your own research for more clarity.
Let me start by saying this,since bitcoin was first introduced,bitcoin has had a chopy and volatile trading history.bitcoin was designed to be use as currency in daily transactions.bitcoin's price is a product of demand,supply and market sentiment.and let me also remimd you that bitcoin is a cryptocurrency which investors have also used it to store value and hedge against inflation.
I'm now concluding with this,among all crypto asset classes,bitcoin have more volatile trading history.
I can agree that Bitcoin is volatile considering it's adoption rate, and the number of traders constantly active to trade on a daily base. But not as volatile as some of these shitty coins we've today that can turn into dust in a blink of an eye. Bitcoin has a very crazy supply and demand rate, which keeps helping it to create more liquidity. Even Bitcoin's market cap compared to the others has a very strong margin, so even to the least investor has nothing much to fear, compare to when he/she invest in some meme.
And you pointed out that investors use Bitcoin as a store of value. Well, it kind of fit that description, but is Bitcoin actually a store of value?. From what I know, anything with store of value is something that can retain it's worth or purchasing power over time, but Bitcoin happens to beat that description, as it doesn't only retain it's value, but it also increase in value as well. Another phrase might just sound cool, rather than the "store of value".
