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 feel unsure of global regulation. Let's see the regulations in one country alone, it's still complicated about the decision to bitcoin. How will it be if many countries are formulating it? It will take quite a long time, and frankly I feel a little pessimistic about the universal regulation of bitcoin but if it works, then the development of cryptocurrency will become more rapid.
