Yeah,so the buyer will have to buy 73 bitcoins from some crypto exchange platform and probably pay some
"handsome" fees.

I assume that this man is selling some overpriced real estate he doesn't need just for the sake of getting Bitcoins and joining the the bullish rally(which kinda ended yesterday).
By the way,nobody would be that stupid to pay 70 BTC,because the Bitcoin price might unexpectedly go up to 12K USD again,so the potential buyer will lose potential profits of HODLing that BTC and selling it for fiat.
