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.
it is not a legit state currency but bitcion is a legit crypto currency. The concept of crypto currency was made only on the virtual world yet it can still be converted into state currency which made it legit and reliable.
