Bitcoin is a digital currency and it can go up and down but I think Bill Gates shouldn’t comment like this. And I think people who are investing in bitcoin are wise enough to understand what they are doing and where they are investing.
That is really a absurd situation you are talking about. I see no chances of internet being destroyed . If this happens then cryptocurrency will not work as it is totally dependent on network. But if this happens then not only cryptos but many more sectors will stop.
