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?
There will be available cash to buy bitcoin and satoshis. There will be a moment when the richest guy or guys together won't be able to buy the whole supply (no one is able at the moment too).
I have one question for you: How much gold do we have right now in overall? A lot, yeah? And did gold cause fiat crisis? No. If we define bitcoin's price into USD or fiat, then how will we have fiat crisis? There won't be a similar moment.
If fiat will be defined in bitcoin and bitcoin's value will skyrocket, i.e. one snickers will cost 0.00001btc instead of $1, then maybe we will have the fiat crisis.
