## — Methodology —

Price points are anchored to month-end USD spot at ~6 dates per year (CoinGecko historical). Each simulated monthly buy uses the most recent historical price ≤ the buy month. Excludes exchange fees (assume 0.1% maker — adds ~$50 of drag on a $100/mo × 6yr run). Current value uses our April 2026 anchor at $112,000.
