Retired now with 12 BTC?

Would you consider feasible a permanent retirement with 12 BTC starting now?

The rationale:

Spending (no yield) as purchasing value increases. For 70 years max.

Expenses equaling $70k / year or more in today’s purchasing value.

Expenses per year:

• 2025 - 0.5 BTC
• 2026 - 0.8
• 2027 - 0.8
• 2028 - 0.8
• 2029 - 0.2
• 2030 - 0.3
• 2031 - 0.3
• 2032 - 0.3
• 2033 - 0.07
• 2034 to 2044 - 0.05 per year (0.5 total)
• 2044 to 2094 - 0.01 per year (0.5 total)

This would leave over 5 BTC for one time purchases of

• house of 1M+ ( 1 BTC after 2033)
• car 0.5
• kids education like supporting for study: 0.5
• apartments for rental yield: 2 BTC
• extravagant expenses: 1 BTC

Does this sound remotely realistic?
