25 Years: From 40 to Retired at 65
The difference between retiring at 65 and 70isn't just 5 more years of work — it's 5 fewer years of portfolio growth AND 5 more years of withdrawals. That double impact makes each year of earlier retirement exponentially more expensive.
With 25 years of accumulation starting at 40, the Power Law model projects a portfolio of $15.7M by age 65. This comfortably sustains $60K/year expenses through age 85.
The aggressive all-in Bitcoin strategy concentrates all savings into BTC. This maximizes upside under optimistic models but carries significant concentration risk. Compare with the diversified default scenario to see the trade-off.
