"I like 5% right now… If it goes past that, I sell it down," O'Leary said, referring to how he manages concentrated positions in assets like **Bitcoin** or **Tesla**. He highlighted that no single asset should dominate a portfolio, especially volatile ones like cryptocurrencies. ## **The Tesla Lesson That Changed His Mind** O'Leary also shared a personal story about initially dismissing **Elon Musk's** Tesla before changing course after a conversation with his son, who interned at the company. "It's not a car company, it's a data company," his son told him, referring to Tesla's autonomous driving data network. Shortly before a CNBC appearance, O'Leary said he bought shares on impulse and later saw the investment surge dramatically. Still, he didn't hold indefinitely. "I started selling it and selling it," he said, explaining that he gradually reduced his position to maintain balance in his portfolio. **Read Also: No Need For Stocks: Kevin O'Leary Says You Can Be A Millionaire by Investing 20% Of Salary In This Strategy – 'Just Watch It On Your Phone Grow'** ## **You Can't Go Broke With Cash: Mr Wonderful** O'Leary, popularly known as Mr Wonderful, said his long-term approach was shaped by advice from his mother. "My mother taught me this game. She said, this way you never cry the blues, you always have cash flow, that’s it, you can’t go broke if you have cash," he said. He added that consistently taking profits prevents emotional decision-making and protects investors from major downturns. ## **Kevin O'Leary Net Worth $400 Million** According to Celebrity Net Worth, O'Leary has an estimated net worth of about $400 million. His television breakthrough came in 2006 when he joined CBC's Dragons' Den as one of five venture capitalists. He became known for his blunt on-screen persona, a character he has said was shaped in part by the show's producers. In 2009, O'Leary joined the U.S. version of the franchise, Shark Tank, which significantly expanded his public profile. He appeared on both programs until exiting Dragons' Den in 2014, while continuing his role on Shark Tank. **_Disclaimer_:** _This content was partially produced with the help of AI tools and was reviewed and published by Benzinga editors._ **Read Also: Kevin O'Leary Says You're Not Rich Until You Have '$5 Million Liquid,' Urges Entrepreneurs To Sell Businesses, Chase New Ventures** _Photo Courtesy: Kathy Hutchins on Shutterstock.com_ ### Related Stocks - [TSLA.US](https://longbridge.com/en/quote/TSLA.US.md) - [GBTC.US](https://longbridge.com/en/quote/GBTC.US.md) - [HODL.US](https://longbridge.com/en/quote/HODL.US.md) - [TSLS.US](https://longbridge.com/en/quote/TSLS.US.md) - [BTCO.US](https://longbridge.com/en/quote/BTCO.US.md) - [BITO.US](https://longbridge.com/en/quote/BITO.US.md) - [TSLQ.US](https://longbridge.com/en/quote/TSLQ.US.md) - [BTCHKD.VAHK](https://longbridge.com/en/quote/BTCHKD.VAHK.md) - [BTCUSD.VAHK](https://longbridge.com/en/quote/BTCUSD.VAHK.md) ## Related News & Research - [Elon Musk's Tesla reports unchanged bitcoin holdings, books $173 million digital asset loss](https://longbridge.com/en/news/283723556.md) - [Elon Musk Sides With Viral 'Pokémon Economy' Analogy On Free Markets— 'This Is How...'](https://longbridge.com/en/news/284765391.md) - [EXCLUSIVE-Only Elon Musk can fire Elon Musk from SpaceX, filing shows](https://longbridge.com/en/news/284593138.md) - [The SpaceX IPO could make millionaires.
