POS = Piece of Shit inwardly focused investor coin
POW is mined by hardware but it is much more than just that. Hardware company's, retailers make huge profits off miners and gives them reason to put some profits back into crypto. A profitable coin brings exposure to that coin and crypto in general, it is a driving force that brings lots of new people into the scene. Miners tell their friends and family about crypto and they invest some money into it, when those people make money they tell their friends and more and more people become aware of the tech.
In a sense if everything goes POS then the cryto scene is fucked.
Yeah good points dude (and thanks to everyone else who posted). Makes sense!
