Robert Kiyosaki, author of 'Rich Dad Poor Dad,' has advised investors to wait for potential price drops in gold and Bitcoin before increasing their holdings. Posting on the X platform, Kiyosaki suggested that while both assets are currently trading at high levels, a future collapse could present a buying opportunity. He emphasized the importance of conducting personal research and exercising caution in investment decisions. Kiyosaki also reiterated his long-term bullish outlook on Bitcoin, predicting it could reach $1 million per coin by 2030, and stressed that the quantity of Bitcoin owned is more crucial than its current price.
