3 million initial net worth compounding 10% more than inflation but subtracting $120,000 per year for living expenses ends up at 5.677 million dollars in 10 years.

So 3 Bitcoin at 1 million dollars per coin is more than enough assuming 10% net CAGR and $120k annual expenses. Bitcoin has averaged much higher CAGR throughout its spot price history so that’s a conservatively low estimate.
