Also, unlike stocks BTC has a value outside of what you can sell it for.
You mean intrinsic value? You are mistaken. It's stocks that have intrinsic value (at least good stocks). That value comes from owning market share, production capacity, etc. All value of Bitcoin comes from trust.
That said, trust can be a pretty powerful force.
I know it's debatable, but I think bitcoin does have intrinsic value based on it's utility and privacy. A stock is a promise to pay back with interest on a capitol investment. A promise made by one entity that may fail. Bitcoin has the backing of all it's users and is less likely to fail, because there is no central failure point.
