I think governments around the world NOT having agreed upon how to deal with crypto is one of the most if not the most important thing protecting the space. For the government's point of view, crypto is both a threat and an opportunity. It's a threat because it is hard to control. But it's also an opportunity because it's a new industry capable of generating taxable economic activity. If governments around the world could agree on how to regulate crypto, then the control aspect would be amplified.
