The majority of people on the planet won't actually be able to utilize Bitcoin because not every location has access to the modern internet technologies that we take for granted. Furthermore, not everyone is able to comprehend the completely implemented technology in the majority of countries.

     The only people who stand to gain significantly from Bitcoin are large corporations such as Blackrock, etc., wealthy individuals who are receptive to it, and even middle-class and middle-class individuals who are neither rich nor poor. They will only get or possess bitcoin so long as a purchase is made.
