Bitcoin-Rich Hedge Fund Manager Pays $44 Million for Extravagant L.A. Mansion

Longtime Hidden Hills resident Jeffrey “Jeff” Feinberg is ready for high-flying Brentwood living. The hedge fund guru, 53, has paid $44 million — a whopping $1 million above the property’s initial $43 million asking price — for a Vegas-like contemporary monster of a mansion with seven bedrooms, 11 bathrooms, two swimming pools and countless other amenities, as was first reported by the Wall Street Journal.

Built on speculation by veteran developer Ramtin Ray Nosrati, the flagrantly palatial estate sits behind tall gates and features an array of eye-popping gizmos — a hair salon, a putting green, games room with a high-tech sports simulator and a 1,000-gallon aquarium. There was also, at least at the time of the property’s completion, a rooftop “cannabis garden” stocked with marijuana plants.

Listing details don’t call out the total living square footage, but reports say the place may weigh in at a brain-frying 55,000 — a number that also includes the two-story guesthouse. There’s also a world-class movie theater with a fiberoptic ceiling to simulate a starry sky, like a more advanced version of what you might find in a modern-day Rolls Royce.

The compound is so devotedly garish that just gazing at one room or another is enough to stimulate a sensory overload, but among the myriad other features are a bespoke wet bar hewn from exotic wood and stone, a double-height great room with a linear fireplace set into a monolithic stone wall stretching from the floor all the way to the ceiling, an indoor succulent garden, an indoor pool and wellness suite, an infinity-edged outdoor pool and vast indoor/outdoor living spaces with more wet bars, flatscreen TVs, firepits and numerous lounge areas.

Feinberg, a former managing director at the George Soros-founded hedge fund-turned-family office Soros Fund Management, once had his own investment firm. The $1 billion JLF Investment Fund was shuttered some years ago; the veteran trader now operates Feinberg Investments, a limited partnership that invests his personal wealth. In addition to his hedge fund career, Feinberg also reportedly bet early and big on bitcoin — a move that has paid off extraordinarily well over the past year, a few minor dips excepted.

Feinberg is also known for his love of decidedly immodest homes. Back in late 2019, he famously made waves by selling his $15 million Hidden Hills mansion to YouTube celebrity Jeffree Star. He also once owned a hulking blufftop compound — hewn almost entirely from concrete, no less — atop Malibu’s Point Dume, though that property was sold for $21.8 million, earlier this year, by his ex-wife Stacey Feinberg to a non-famous couple. On Santa Monica’s Gold Coast, Feinberg still owns an oceanfront house that’s currently on the market at just under $11 million, though he paid $12 million for the place less than two years ago.

The Brentwood listing was held by a consortium of high-powered L.A. agents: Branden and Rayni Williams of The Beverly Hills Estates, Shauna Walters and Sally Forster Jones of Compass and Josh and Matt Altman of the Altman Brothers Team at Douglas Elliman.
