I don't think so, think about bitcoin, it is a currency yet popular than the other but still some countries are hard to accept or legalize it. So, i think if you create a new maybe they ignore that too.
If there is no legal basis so it is legal because if you create crypto currency it is just like selling products to the peoples and that is legal on the basis of pre market in a democratic country, if it is just not scam so it is legal.
