The problem with Bitcoin is that there's no good way to calculate how much it should be worth like you can with stocks, it's all just pure guess and the fact how much money can people actually pay for it. Some people say that Bitcoin will be worth $150,000 or $500,000 - but if they truly believe it, why won't they sell all their assets for it?
the same is true with stocks. just because the big players who own the economy have defined ways of their own to calculate price of a stock that doesn't mean there is really a way to do it. stock price is also pure guess.
at least with bitcoin you see the utility and the scarcity then you look at the adoption and how many people can have how much bitcoin then you can come up with a good price.
