In simple terms until it gets a centralized state it will not be given importance as a legal currency. In my thinking it will get the legal status with some sort of limitations depending upon the government. It is legit, as everything happens through internet scamming is easier and this makes people term it as not a legit one.
We can say that Bitcoin is not a Legit one, its because our country or some country did not yet fully accepted it. Even though some citizen of a country used it but as long as the Government did not accept it or do not recognize the value of bitcoin it we can not used it in some transactions. We just have a minimum use of it and as of now, we can not used it everywhere we want.
