World wide regulation would bring bitcoin legitimacy and enable it to get deeper into economy and business which would contribute to further growth and expansion.
But I'm not sure that this project of global regulation will be successful because it's hard to expect that all countries would get alligned regarding question of ful regulation.
I agree with you. I think that the laws adopted will be different in different countries, this can also affect the future fate of bitcoin. I think that it is better for countries to agree on a single concept of law.
