10 Years: From 30 to Retired at 40
The difference between retiring at 40 and 45isn'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 10 years of accumulation starting at 30, the Power Law model projects a portfolio of $1.1M by age 40. 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.
