Bitcoin is like anything else: it's worth what people are willing to pay for it.

Earnings don't move the overall market; it's the Federal Reserve Board... focus on the central banks, and focus on the movement of liquidity... most people in the market are looking for earnings and conventional measures. It's liquidity that moves markets.

Soros has taught me that when you have tremendous conviction on a trade, you have to go for the jugular. It takes courage to be a pig. It takes courage to ride a profit with huge leverage.

I believe that good investors are successful not because of their IQ, but because they have an investing discipline. But, what is more disciplined than a machine? A well-researched machine can make many average investors redundant, leaving behind only the really good human investors with exceptional intuition and skill.

If you're early on in your career and they give you a choice between a great mentor or higher pay, take the mentor every time. It's not even close. And don't even think about leaving that mentor until your learning curve peaks.

I don't think Donald Trump is Ronald Reagan.

I've always loved to play games, and face it: investing is one big game. You need to be decisive, open-minded, flexible and competitive.

With my business, the way you make big money is you find a great management team and a good concept, and you stick to it, and you add to it over time. In philanthropy, there was more this idea that once an idea was formulated, you moved along.

What a company's been earning doesn't mean anything. What you have to look at is what people think it's going to earn. If you can see something in two years is going to be entirely different than the conventional wisdom, that's how you make money.

I think old people like Hillary Clinton and I shouldn't try and be cool with social networks, you know; maybe she should leave that stuff up to Chelsea.

Soros is the best loss taker I've ever seen. He doesn't care whether he wins or loses on a trade. If a trade doesn't work, he's confident enough about his ability to win on other trades that he can easily walk away from the position.

In my experience, the more successful an idea is, the easier it is to fund it. In philanthropy, it's almost harder.

There's just nothing to me so invaluable in my business, but in many businesses, as great mentors.
