I really question the whole "World Leaders" part of that statement. They may be seen as "leaders" but I see most of these people as "chair warmers". Regulation is only good if you truly understand what you are regulating. I don't see that from these people at all, I see fear and that is dangerous. We as a group, as crypto users and leaders, need to constantly push our message on why crypto is not a threat to these people if they embrace it. On the other hand, if they fight it, it will only go underground and become a weapon, and an unstoppable one at that.
It may be hard to believe that very often people expressing a strong opinion against digital currency don't understand the very basic concept of DLT (Distributed Ledger Technology) operating in a peer-to-peer setup with no single point of failure. It cannot be controlled or destroyed - hence unstoppable.
