I think for it to be in full state regulation, because every country has different legal rules, but if it is not used for negative things I think it will not happen.
If your country banned the used of bitcoin it means that it prohibits you to trade, sell or exchange your bitcoin. But it usually depends on how the rules imply in your country since every country has a different legal rules. It may send you to jail or being punished if you are caught using or trading bitcoin.
