If that will happen, it's a sad story. It's the end of bitcoin
Bitcoin will breakdown. All transactions, trading and even mining any crypto is done by the help of the internet. No internet, no bitcoin. No bitcoin, no profit chance. That's it, the end.
Not only the end of bitcoin, it will be a lot worse. The end of technology!
