It's funny that everyone says pretty controversial things. Some are sure that in the event of a global global military conflict, cryptocurrencies will be a priority, while others say the opposite.
Personally, I believe that if all of us turn off electricity, then we will return to the Stone Age, where we will not have time for cryptocurrency.
Moreover reason we don't hope to see a world war 3. There is nothing fun about it. Many believe that if there is one, cryptocurrency price especially Bitcoin will rise. But what's the need of having a raised price in Bitcoin when everywhere is in conflict. When electricity is down, spending Bitcoin becomes difficult.
