If everything else fails, I know I can still have two things to pay with: cash and crypto.
Good luck buying groceries or paying the mortgage with Crypto.
Bitcoin doesn't store any energy.
Bitcoin is like a F1 car going around a track forever, with your name scribbled on it.
(You conveniently left out “cash” from your reply. Cash. I’ll buy groceries with cash, if I can’t use my card.)
I think of them as representations of the idea that energy is (currently) so abundant and cheap that we can waste it on mining things like gold and crypto, a fundamentally ridiculous concept in terms of real actual human needs.
Once that stops being the case (when fossil fuel starts running out globally), the whole thing - cash, gold, crypto, stocks, bonds, property - everything falls apart.
If "everything else fails" the internet has failed, and crypto will be worthless. Gold will probably still have some value, unless shit really hits the fan.
It's a sort-of flex, showing off, a demonstration of (energy) wealth. Humanities's peacock feathers.
Bitcoin is valuable because people accept that it’s valuable, same as with cash, gold, crypto, stocks, bonds, property. The price of an apple is $2 is because I offered it to you for $2 and you bought it.
Gold is a bit different. You could stop mining it today entirely and you could still have a gold currency. Stop mining bitcoin and it all effectively disappears!
