Billionaire Grant Cardone has announced he is listing his Golden Beach mansion for 700 Bitcoin, contrasting with his neighbor's decision to sell a similar property for $88 million. Cardone expressed confidence in his choice, stating, "Let the neighbor take more fiat, I’ll still be better off 4 years from now." This move highlights Cardone's bullish stance on Bitcoin as a long-term investment, as he opts for cryptocurrency over traditional fiat currency in this high-profile real estate transaction.
