Regulation is something that we're seeing on a massive scale right now. And you're right that it's something global, not just one country is doing it, but every single country has been tightening up on their regulations due to the 2017 bull market.
This is something that can't be prevented. Regulators will do this sooner or later, and right now, it's happening.
However, is it really going to affect bitcoin itself that much? Opening and operating exchanges may be harder, and trading fiat/BTC pairs will be too, but that's about it. The regulations aren't really about bitcoin itself, but rather about bitcoin third party services.
I agree! This issue is something uncontrollable, and global regulations may have less or greater impact in the way bitcoin operates. Bitcoin is not controlled by a single institution, it can provide easy transfer and has no middlemen, unlike government that has central command.
The challenge is that government can't regulate bitcoin, but it can restrict its functionalities like not accepting it as a mode of payment and other factors that can hinder its operation. However I don't think it can bring bitcoin to death in the global market, because I still believe that bitcoin is still backed up by strong developers and the trust of the public is increasing rapidly.
