Robert Kiyosaki, renowned author of 'Rich Dad Poor Dad,' has reiterated his commitment to investing in Bitcoin, citing four key reasons. Kiyosaki points to Bitcoin's scarcity, its fixed supply cap of 21 million coins, increasing adoption, and market psychology as driving forces behind its value. With Bitcoin currently trading above $100,000, he emphasizes the importance of its limited supply and the growing interest from institutional investors as significant factors for its long-term potential.
