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.
Bitcoin has it so called feature, decentralised control. Who would let something legal without having the right to control it? In my opinion, that is one of the reasons why bitcoin isnt legal on certain country and isnt a legit currency as well.
