there doesn't have to be some evil forces hard at work to make people want that profit (in fiat terms). it is the people themselves who saw the gigantic rise and slowly forgotten the real reasons why bitcoin was created. a quick look at the past 10 years can show you that price has gone up a lot. if we assume initial price was $0.01 then price has gone up 200 million percent! that is 55k% per day. such rise is bound to attract "speculators" who want their fiat multiplied.
BUT none of that changes the nature of bitcoin from being a currency though.
