Sure, it's worth billions just like someone thought Uber, Groupon or WeWork was worth billions. In Bitcoin's case, it's distributed consensus. In the case of startups, it's the investors that control consensus. In the case of the market, it's the market manipulators that do it, in conjunction with public opinion. As long as public opinion holds that Bitcoin is valuable and it continues to be a secure solution that doesn't require edge case handling (which increases risk) then there's no reason anyone shouldn't think it's a reliable store of immutable values in the near term.
