Story goes explaining that they need an internet access in order to buy this virtual currency that they can use for e-commerce, or transacting with other people and it is
like sending messages but instead of strings of characters, they can only send numbers in which are called Bitcoins. Another is that
bitcoin is like Fungus.
“Fungi don’t have a central ‘brain,”
what is there is a decentralized networks that shares the same information, the same with fungus having a characteristics of
"resource management, reproduction, and defense strategy.”
Fungi are also undying as after the five mass extinction, they still remain on earth. That's how powerful bitcoin network is.
Bitcoin existed for only 10 years, and it didn't face too much adversity so far, so any claims that Bitcoin is indestructible are purely theoretical. Bitcoin didn't witness a nuclear war, a mass extinction, an alien attack, a global ban by governments, a 51% attack, a critical bug in its protocol and lots of other threats. And however small it might be right now, there's always a chance Bitcoin will get replaced by a different coin or a whole new tech.
P.S. you have posted a link to Roger Ver's bitcoin.com website, which is an anti-Bitcoin platform that scams people by claiming that their shitcoin bcash is the real Bitcoin. Don't do this.
