What if?

  1. The question

    What if I bought Bitcoin instead?

    $500 every week into Bitcoin since 2015 versus the same habit in the S&P 500. Same calendar, two assets, real weekly data.

  2. Assumptions

    What this page actually assumes

    • Bitcoin DCA, $500/week, held. Not trading, not leverage, not a basket of alts.
    • Comparison is the identical contribution schedule in the S&P 500.
    • Start year defaults to 2015. Later starts drop the early cheap-Bitcoin years on purpose.

  3. Historical data

    2022-01-07 → 2026-08-28

    Bitcoin’s weekly series in this product begins in 2015. That is already a strong-history sample (low prices, then a cycle, then another). It is not 2009, and we do not back-fill those years.

    Series: Bitcoin and S&P 500. Same contribution calendar. No data before 2015.

    What the numbers say

    The Bitcoin habit and the index habit are not “risk-adjusted the same.” This page only answers the dollar question: same cash, two tickers, hold to the end.

    What if the weekly amount wasn't always the same?

    These pages fix the contribution. SteadyGrow keeps the same long-term budget and sizes weeks from valuation — more when markets are cheap, less when they're stretched.
