if by "legitimate" you mean something that the government approves then you are wrong this is not the bitcoin goal either.
Why would anyone assume "legitimate" means "government-approved"? Legitimacy is not a legal concept.
well English is my second lagnuage and according to Cambridge dictionary "Legitimate" means "allowed by law", and who sets the law but the government?
if you meant something else then i am all ears.
there is a simple explanation for it, people don't care about altcoins!
We heard the same about Bitcoin...
we hear a lot of things about bitcoin...
