A scam project will not stand the test of time like ethereum have done and it will also not have given people much profit like it has done.. So if you still feel it is a scam,keep your opinon to yourself.
Good answers, especially legalization of ethereum companies that have been legitimately professionally and as you mentioned it has been more than 5 years. every new company if it can made 5 years running then I make sure company is bonafit or successful and mutually beneficial to all parties, not only developers who feel it.
