Robert Kiyosaki, author of "Rich Dad Poor Dad," announced on X that he sold Bitcoin purchased years ago at approximately $6,000 per coin for $90,000 each, totaling about $2.25 million. Kiyosaki plans to use the proceeds to acquire two surgical centers and invest in billboard advertising, expecting to generate around $27,500 in tax-free monthly cash flow by next year. Despite the sale, he remains bullish on Bitcoin and intends to reinvest in the cryptocurrency using the new cash flow.
