I don't know how they are going to make it regulated in a way. Or in a way, does bitcoin need to be regulated in the first place? Even if they have managed to do that, what impact would it bring especially when you already have tons of other bitcoin exchangers around.
So do you want the exchanges to keep going down? People who are from the US and trade even here can get arrested (look at BurtW).
The exchanges have to legalize their trading of fiat.
