I don't really care if bitcoin have benefited the world economy or not but what I know is that bitcoin have benefited lots of people,  not just only the early adopters but Real holders. There is no doubt that bitcoin serves as a store of value real holders and it has really improve alot of people financially. Only people who don't have understanding of what bitcoin is will criticise bitcoin and think it has no value to someone financially.  For me I think if bitcoin is serving as a store of value it is solving economical problem , it doesn't mean it must be country problems . This value is what the government can't give to it citizens but bitcoin hodlers are get value in bitcoin that means it is helping the economy somehow by adding value to individuals financially.
