> crypto is the mean of payment (at least Bitcoin was designd to serve this purpose). stocks are the mean of investment and control (if you have enough of them).
> holding bitcoins do not give you the passive income (if you do not lend it) but the shares do (in form of interest).
> recent attraction to bitcoin from institutianal investors is purely speculative. they buy in hope the price will rise (the same they  do with shares of prospective companies). they will start selling as soon as they smell the rubber burnt. BUT the number of coins is limited as the number of shares of very prospective, attractive companies. so the rubber most likly won't start to burn in near future, unless the more attractive player in form of cenrtralized crypto will come. in this case the money will flow from one glass to another.
SO. at the moment bitcoin is more like stocks rather then the mean of payment ( people/institutions buying and holding it like praceous shares of promicing hi-tech company). hopefully this will change when
>> the institutional flow go away in the hunt for another speculative mean of easy gain;
>> the bitcoin ecosystem do mature enough;
>> the cryptocurrency payment infrustructer do evolve and drive out the obsolite one;
>> more indivuduals come on board (bitcoin belongs to people but not the institutions).
