Sorry if the topic sounds logically flawed I didn't dig much deeper into the financial fantasies of such.
I'm wondering what if one day Bitcoin goes so high up in value that it causes somewhat a fiat crisis? I mean imagine, you've Bitcoins but there isn't much cash available in the market to buy your BTC, or simply put people can't afford it? Will bitcoin be of any value then?
Well in that case they can use other assets along with fiat for buying bitcoin.
Imagine paying few billion dollars along with a house (real estate property) for few bitcoins.
or
Imagine paying few billion dollars along with gold for few bitcoins
Not only assets but also things like cars, motorbikes, ships, planes etc...
That's the specialty of bitcoin

Bitcoin can be bought with anything.
