Adam Bergman explains how self-directed retirement accounts let you invest beyond stocks and build tax-advantaged wealth. A self-directed IRA can hold alternative assets like real estate, private equity, gold, or Bitcoin. He stresses the three big prohibitions: life insurance, collectibles, and any deal that directly or indirectly benefits you or close family. For entrepreneurs, he gives three funding options: invest if you own under 50%, borrow up to $50,000 from a 401(k), or use a ROBS rollover so a new 401(k) buys your company's stock. He also flags pitfalls like UBIT and the need for extra due diligence with private deals. To show compounding, he compares $3,000 per year from age 25 to 72 at 8.5%: about $1.97 million tax-free versus roughly $812,000 after 25% annual tax. The takeaway is to trust the retirement system's tax shelter, save consistently, and invest in assets you actually understand.
