Reality Check
Buying 1 BTC outright today costs $66,926. DCA'ing $400/month costs you $240,000 total under the Power Law model — costing more because you're buying at progressively higher prices.

How is This Calculated?
Each month, your $400buys a fraction of a Bitcoin at that month's projected price. Under models where BTC price rises (Power Law, CAGR), each dollar buys less BTC over time — so earlier contributions are worth more. The “flat price” column shows the baseline if BTC stayed at today's $66,926.
The 2.1 BTC milestone represents one ten-millionth of total supply (21M ÷ 10M) — a symbolic goal in the Bitcoin community. Reaching “whole coiner” status (1 BTC) is the most common aspiration for long-term DCA investors.
