Bitcoin is primarily a store of value, similar to gold
Hi owlest
I think we should think about what store of value means.
Functioning as a store of value depends on volatility/stability (of purchasing power).
Being a store of value has nothing to do with the price going up or down.
Being a (good) store of value and volatility... don't get along...
The more stable the purchasing power of a currency is, the better that currency functions as store of value.Ordinary people and businesses - i.e. those getting that payment - don't want to carry the risks connected to volatility.
In receiving that payment they want to become neither speculators nor investors.
They just want to get paid and they want to know what that amount of money will be able to purchase next week, month, year...
They prefer predictability to the chance of big gains.
The need that kind of financial security.

The fact that BTC has allowed bigger gains (... to those who bought and sold at the right moment...) than gold is completely irrelevant: gold is - by far - a better store of value than BTC because it's purchasing power is more stable than that of BTC.
