On "The Rich Dad Radio Show" in recent weeks, Robert Kiyosaki highlighted the impact of higher food and fuel prices, as well as the fact that gold and silver are a better investment than cash.

The author of the book "Rich Dad Poor Dad" warned that bear markets can be a wake-up call for investors and that economic downturns are rare opportunities to scoop up bargain assets.

Here are Kiyosaki's 10 best quotes, lightly edited for length and clarity:

This is the first thing. I am a trader of bitcoins." I don't think it's worth anything. I don't pay attention to what's happening in the game. May 11th

There are two Savers aren't winners." Why don't you save money when they print them? I don't understand it. May 25th

There are three. The US dollar isn't real. It is a piece of garbage. I own gold and silver because of that. I want something tangible, I want oil, and I wantfertilizer, because they do something. May 11th

There are four. The only people that control money are governments, tyrants, and dictators. The US Treasury and the Federal Reserve Bank are mentioned. I don't trust the government and that's one of the reasons I own gold, silver, and digital currency. I don't think the Fed is trustworthy. I don't think the Treasury is trustworthy. May 11th

There are five. Nobody else is involved with the gold coin. There's nothing like the Wizard of Oz. May 11th

There are six. People are being wiped out. They're being killed by inflation. That's what scares me. June 15 is the last day of the year.

There are seven. You could be stupid if you put your money on Apple and you get rich. I know what I'm talking about. The bear market shows you that you're dumb. June 22 is the last day of the year.

There are eight. Remember, the bull goes up the stairs, and the bear comes out the window. The bear is going to jump. Bull markets rise gradually, while bear markets fall suddenly.

There are nine. There will be more bodies floating to the surface. The possibility of bargains emerging and businesses failing during an economic downturn was highlighted byiyosaki.

There are ten. The people are crying. You will see a different world if you understand that it is all in your head. Today there's more chance. When investors could be excited about the discounted assets likely to emerge,iyosaki was referring to them.

In a worst-case scenario, the stock market could fall another 20%. It is possible to know when the market has reached rock bottom.
