Robert Kiyosaki, a well-known financial educator, advises diversifying investments with gold, Bitcoin, and silver, emphasizing Bitcoin as the most promising asset due to its limited supply of 21 million coins. According to NS3.AI, Kiyosaki criticizes the unlimited supply of gold, which can be increased by miners, potentially impacting its price stability. He also expresses a pessimistic view of the US dollar and discloses a substantial purchase of silver, predicting its price could rise to $200 per ounce or more by 2026.
