Salt was a pretty popular currency in a lot of places at some points in time.

Also totally unrelated but speaking of shells and beeds I had a random thought regarding pearls.

Pearls are way rarer than gold.

And if you consider that one day the earth will be consumed by the sun and assuming life on other planets doesn't exist, one day pearls will stop being generated.

So therefore, Bitcoin is like digital pearls rather than digital gold which is incredibly abundant and will continue the be created as long as stars big enough exist.

He's right though, as long as civilisation isn't wiped out I believe Bitcoin is the future of money.

Even if the governments force stable coins on us those stablecoins will be backed by Bitcoin.

USDT would be backed by Bitcoin instead of USD etc.
