Your first 5 years of aggressive saving carry more weight than the next 15 combined. I walked through the math on the Future Signal podcast with Jarrett Carpenter. When you time-box a 4-5 year stacking sprint — cutting expenses with intention, automating bitcoin purchases, tracking your FI number weekly — you build a compounding machine that does the heavy lifting from that point forward. Every $1 cut from monthly spending drops your FI target by $300 at a 4% withdrawal rate. Funnel that into bitcoin while central banks keep expanding the money supply, and you're compounding on two axes: your accumulation rate and the asset's appreciation. Traditional FIRE planning also misses a critical pillar: sovereignty. Stocks and bonds are IOUs gated by intermediaries — SVB showed us that access risk isn't theoretical. Bitcoin in self-custody means no one stands between you and your wealth. I break all of this down in one of my FIRE BTC deep dives — sprint mechanics, sovereignty in practice, and how AI reshapes the path to FI. 🔥 https://firebtc.io/p/icymi-leveraging-bitcoin-to-find
