Do we need to regulate crypto so that more countries will allow it?
No, it needs no regulation. Even if you want to, how are you going to do that? 🤔 I dont see it possible in anyway at all. Any country that doesnt want to allow the use of Bitcoin is their own choice, you cant force them to do so. Bitcoin is meant to be used by people and it gives them complete control over their money. So you shouldnt be expecting regulation, its not going to happen at all.
Regulation will help the investors to protect from the scam ICO's because the government should come up with a solution in order to protect investors. Of course, it is not easy because people are losing their hard earned money by adding some rules and regulation to the ICO's.
