The best-selling author of Rich Dad Poor Dad, Robert Kiyosaki, has revealed that he is waiting for the next pullback before investing more in Bitcoin. After predicting a “giant stock market crash” that could also tank the crypto market, he said that Bitcoin's future is “very bright.” Kiyosaki took to his official Twitter handle and wrote, “Hooray. Bitcoin rising above $60,000. Future very bright. Celebrate yet be cautious. I am waiting for a pullback before investing more.”
