Regulation is a good thing it makes usage of bitcoin beneficial for the government and citizen but at the same time it looks opposing the basic nature of crypto currency that is decentralization.The crypto was found to be used as a currency without any intruder in between,now government will record the transactions by means of regulation.So we have to pay taxes and other stuffs to the government as using fiat money.But regulation will protect(maybe) the crypto currency market from illegal activist.So it is a good thing right for the government and for the citizen also.
I think if the crypto currencies were totally regulated the people may lose their interest on using it because it also looks same as using fiat.So there maybe more price fall in crypto market if more countries regulate the usage.
This is why the concept of cryptocurrency can be quite complicated, you enjoy freedom through decentralization but it comes with the price of being unprotected which can bring you so much risks that you may end up with nothing in the end due to its ambiguity. In your mind, clashing thoughts would be prevalent and you'll be thinking of what's more important to uphold but at the end of the day, it's the challenge and risks you're willing to conquer and take that over powers any decision. As supermine mentioned, Bitcoin is a decentralized platform. Establishing regulations would defeat this purpose making it not the genuine Bitcoin that most people know about. On the other hand, regulations are what would protect you if something unfortunate happens in this venture, a must in transaction you do. Take your pick in what suits your situation, otherwise try to make both aspects work harmoniously to have a win-win situation.
