Retiring at 48 with Bitcoin
Retiring at 48 means just 18 years of accumulation starting from age 30. This is an aggressive early retirement timeline that demands higher savings and growth rates.Under the Power Law model, your portfolio reaches $2.7M by retirement — comfortably sustaining $60,000/year (today's dollars, $8,512/month inflation-adjusted) through age 85.
A traditional 60/40 portfolio reaches only $913K by age 48. The CAGR 20% model (a more conservative Bitcoin projection) yields $1.7M.
