you got something wrong! not "everyone" thinks that. and that is why bitcoin is strong. and it is not just something you invest in and make profit. it is a unique decentralized payment system that can not be controlled, censored, restricted, or anything like that. and all of these attributes are making it strong. these are the reasons why more people are going to buy (aka dump their centralized fiat for decentralized bitcoin) bitcoin and why its price will go up. not because there is more profit on their centralized fiat.
