Author of “Rich Dad, Poor Dad”. Robert Kiyosaki has said that many investors are not paying enough attention to a well-known precious metal and are missing out on an investment opportunity.

In a Twitter post, Kiyosaki agreed Andy ScheitmannPresident of precious metals investment firm Miles Franklin that silver is the most undervalued asset in a generation.

Kiyosaki recommended silver as a better investment option. Last year, in one of his tweets, he said, “To capitalize on the US dollar’s crash, I bought a lot more US silver Buffalo cartridges. Silver is a bargain.”

He predicted that silver would trade sideways around $20 for three to five years and then rally to $100 to $500.

“Anyone can afford silver, even the poor. Collect silver now,” he said.

Kiyosaki has warned that the world economy is on the brink of collapse and the country could experience a condition similar to the Great Depression of the 1930s.

“Please. Please please. World economy on the brink of collapse. Keeping going on banks? Savings frozen? Next bail-ins?” he tweeted. “You can buy a real silver coin for about $25. Please pay attention.”

“For years I’ve said, ‘Saving money and investing in a well-diversified portfolio of stocks, bonds, mutual funds and exchange-traded funds is risky advice.’ Today, [it’s still] very risky advice. I still believe that gold, silver and bitcoin are best for unstable times, although prices will rise and fall. Take care,” he tweeted.
