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.
If we goes to the definition of legitimate or legit, it is lawful or somewhat authorized. As per the current situation of bitcoin, it is not legit because there are lot of scams. It is happening that is why it is as of today. But if we look on the brighter side of it, bitcoin is really something. Where we can lean on.
