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.
Some kind of limitation will be there definitely if bitcoin has to go under regulations and that is the main target of politicians and governments to allow use of bitcoin under there nose as they want and it will have to happen if bitcoin should continue in the future with the rest of the world but will it be valuable and useful as it is now after it goes under regulations and that is something we should discuss
