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!
Yea and without electricity and internet u also don't have access to banks and all businesses will die not just BTC

Without electricity and Internet nothing is possible at present. Each and every activity that human does will get connected to internet in one way or the other. So, these reality facts won't let the bitcoin get shut down.
