Your Bitcoin Retirement Plan Starting at 47

At 47, you have 18years until a traditional retirement age of 65. That's 18 years of compounding — and with Bitcoin in your portfolio, the math looks dramatically different from a traditional 60/40 allocation.

What the models say

Using the Power Law model, your portfolio could grow to $2.7M by age 65. Of that, 0.279536 BTC (worth $2.0M at a projected price of $7.2M) would make up 75% of your total holdings.

By comparison, a traditional 60/40 stocks-and-bonds portfolio with the same total savings would reach $913K — that's 2.9× less. Even with the more conservative CAGR 20% model, your Bitcoin allocation pushes the total to $1.7M.

Sustainability check

Good news: under the Power Law model, your plan is sustainable through age 85 with annual expenses of $60,000 (adjusted for 3% inflation). You'd have a monthly budget of $8,512 in retirement — equivalent to $5,000in today's dollars. Your maximum sustainable annual spending would be $156,6672.6× your planned expenses.

The 47-year-old advantage

Starting at 47 gives you 18years of compounding. Each year of delay costs significantly. These projections use mathematical models, not crystal balls. The Power Law model has tracked Bitcoin's historical price well, but past performance doesn't guarantee future results. Bitcoin remains a volatile asset — your actual returns will vary year to year.
