Well, no electricity, and no internet connection would kill BTC for sure! You wouldn't be able to make any transactions without these.
Other issue can be all the countries in the world ban BTC, but this will not restrict it's circulation, as no internet connection do!
These are from technical/logical point of view. However what's most important here is I don't really think that Governments don't really want to kill it. The CEO of VISA said crypto is run by dirty politicians and I do believe that too! They wants to make money out of this game. And at least for this reason this Monkey Business kind of economy is not going to get shut anytime soon IMHO.
