But given bitcoin's volatility, is it suitable for a store of value? I don't think bitcoin is suitable as a store of value, gold would be more suitable for this role. The value of bitcoin is very volatile, using bitcoin to store assets or save is not appropriate and too risky.
Then what's the main reason you buy Bitcoin?
Gold and other commodities price aren't that stable, you can check the price and you will see there was a dump during bad economy season. Bitcoin is also similar it's influenced with bad economy season, but there's 4 years cycle where the Bitcoin price will increase.
I believe most of people buy Bitcoin for investment which is a store of value, do you use Bitcoin as a currency?
