[...] store of value is just one very important property of currency and bitcoin is great at it.
Hey hey... what are you talking about? A store of value is good when you can store value in and retrieve it out when you need it. Bitcoin is a great store of value only if price constantly rise amiright? But, today, will you store your wealth in bitcoin? Hell no, because it can drop 5% or more in a day like nothing. And who want to lose 5% or more in a day? Nobody. When/if bitcoin price gain stability (or start ever-increasing again) then it will become a great store of value again. But not now. BTW i do understand bitcoin usefulness and actually use it, only not as a store of value (obviously).
