How to read it
Rows are weekly DCA amounts ($25 to $1000); columns are target BTC (0.05 to 5). Each cell is the years-to-target under the OLS power-law projection. Color buckets - green < 2 yr, yellow-green < 5 yr, yellow < 10 yr, orange < 20 yr, red ≥ 20 yr - let you spot your row and find the fastest reachable target at a glance.
A dash ( - ) means the target isn't reachable inside 50 years at that DCA rate - try the next higher row.
The model behind it
Forward numbers come from an OLS power-law fit of log10(price) against log10(days since 2009), across all 5,879 days of daily history. The assumed price on day d is 10^(-16.381 + 5.651 · log10(d)), and each weekly buy compounds into the running BTC total.
A curve fitted to the past is not a prediction of the future. Treat these as one scenario, not a forecast. 100,000,000 sats per BTC. Not financial advice.
