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!
Very well said. I agree with you ! Bitcoin will surely be completely shutdown if that will happen. We all know that internet is one of the ways on how to access the bitcoin and if there was no gadgets and electricity, internet is also unaccessible. Bitcoin will completely vanish if governments of each country ban it as what stated above. I also want to add, if no one will support it bitcoin will definitely die.
