We know that Bitcoin is easier to access using the internet, including all transaction needs... however, that doesn't mean Bitcoin can't be transacted without the internet.
If you look at the impact of the internet on cryptocurrencies today, it is huge. And what happens if the internet is lost???
Will you regret owning Bitcoin now? And will you fall into poverty seeing that your assets cannot be sold on any exchange?
What happens if the sun unleases the largest electrical emp ever frying all electronics.
Basically this is your question.
This is the only way the internet would be fully and completely shut down.
If this happens the human race will suffer huge death rate millions maybe billions will die.
Besides crypto most banks will lose all their records. I would simply give my wife a hug check onmy guns and wait for the riots.
My wife and I would most certainly die. As would most if not all-of us on this thread.
To survive you need to have been underground in a shelter so some would live. lost crypto would not be the worst problem.
