Bitcoin education through contrast and clarity

Understanding money requires seeing what makes it work - and what makes it break. Each interactive exploration below examines a different dimension of Bitcoin through the lens of fundamental tradeoffs, irreducible design, and philosophical contrast.

Recent updates
6/4/26 New: Bitcoin vs. Rental Property — the honest yield comparison once landlord costs are surfaced. Walks through the gross-to-net waterfall on a typical rental (vacancy, maintenance, property tax, insurance, management, CapEx erode roughly half the listed yield) and the tax asymmetry on exit (depreciation recapture and transaction costs on top of LTCG, versus bitcoin's LTCG-only sale), then contrasts with bitcoin-treasury yield instruments (STRC, SATA) paying 10–13% under the same ROC tax shield real estate uses for depreciation. Four operational paths from rental property to bitcoin, plus an interactive calculator anchored to the Power Law channel that models your specific situation across three bitcoin scenarios (stay at current multiple, revert to trend, reach upper channel) and four exit paths (full sell and reinvest, partial sell, keep some + sell some with a coupled property-count slider, full keep with bitcoin in addition). Now featured on the homepage as a concept card under The Numbers and as carousel slide #3 (storm-to-sun field — storm reads as the landlord burden, sun as bitcoin's quieter yield) 5/31/26 New: Start Here — a curated orientation pathway for newcomers. Seven explorations sequenced so each one earns the next (framework → emotion → quantification → introduction → mechanism → evidence → commitment), with explicit payoff per step and an applied-next-steps block at the end. Linked prominently from the homepage hero for 'New to Bitcoin?' visitors 5/30/26 The Gallery is now featured on the homepage's Latest section — a curated vertical scroll-through of the ten most striking charts across the site, each chart full-size with editorial framing. Designed as the highest-level entry point for any skeptical reader who wants the structural argument at a glance 5/30/26 The Gallery now ships with the full SEO + social-card baseline that other pages on the site have — Google Analytics, canonical URL, full Open Graph and Twitter card meta tags, JSON-LD WebPage schema, custom OG image (the Power Law channel as hero with editorial chrome), sitemap and llms.txt registration, and reciprocal Related cross-link cards with The Power Law, Bitcoin vs. The Stock Market, and The Bitcoin Horizon. Brings the page into compliance with the site's NEW_PAGE_CHECKLIST 5/30/26 Small fix on The Bitcoin Horizon: the §2 chart caption (under the rolling-CAGR chart) was constrained to 72 characters wide and stopped well short of the chart's right edge. Removed the max-width — caption now flows to the full chart-panel width, matching the chart canvas above it 5/30/26 Gallery polish: Chart 10 (Volatility Is Not Risk) and the matching chart on The Bitcoin Horizon now compute stats from January 2015 onwards — deliberately setting aside the parabolic 2013 run and 2014 drawdown as unrepresentative of plausible forward outcomes. The same 2015+ window is applied to the S&P 500 for an apples-to-apples comparison. The conservative framing strengthens the case: bitcoin's worst-case at 3 years and beyond stays positive, and the 10-year band collapses to a tight 64-85% range, still well above the S&P 500's 13-15%. Chart 1 (Power Law Channel) also gets a 'you are here' pulse halo on the today point — the canonical animated amber marker from STYLE_GUIDE §6.23 5/30/26 Gallery polish: Chart 8 (Heatmap) gains a Period return / Held to today toggle matching the source-page /heatmap behavior — defaults to discrete-window (more informative) but lets readers flip to held-to-today to verify most red cells turn amber when the holder simply kept holding. Chart 10 (Volatility Is Not Risk) legend restored to all four entries — the orange and white median dots now have legend labels 5/30/26 Gallery v2 complete. Final three charts live: the Bitcoin Heatmap (BTC vs S&P 500 outperformance grid, every entry month × every horizon since 2011 — long-horizon rows are amber to the edge), the Half-Life of a Dollar (fiat purchasing power decay; $100 → $50 in 11 years at M2 inflation), and CAGR Ranges by Horizon (Volatility Is Not Risk — how 1y bitcoin variance compresses to a narrow positive band at 5y+). All 10 charts shipped; the Gallery is a full scroll-through of the site's strongest visual arguments 5/30/26 Gallery Chart 7 rebuilt: replaced the $10K-invested-in-2010 lump-sum wealth chart (structurally a cherry-pick of the earliest possible start year, implying returns that won't repeat) with a rolling 4-year CAGR comparison — bitcoin vs. S&P 500 TR vs. NASDAQ-100 TR across every 4-year window from 2017 to 2026. The new chart shows bitcoin's returns declining over time (as the Power Law projects) but still exceeding both equity comparators in every window — even the cycle-top-to-cycle-low 2021-2025 window where bitcoin's 16.7% beat the S&P's 11.1% 5/30/26 Gallery polish pass: stronger section dividers between charts so the eye gets a clear break between arguments (was near-invisible at 4% opacity, now 10%); Chart 2 title now reads 'Bitcoin's Power Law Implied CAGR vs. the S&P 500' (was missing 'Bitcoin's' so the comparison wasn't explicit); Chart 2 convergence footnote rewritten with concrete claims ('more than 2× the S&P 500's 10% benchmark', 'even out to 2150 still sits above 10%') replacing vaguer earlier wording 5/30/26 Gallery Commit C: three more charts live. Global housing affordability across HK / Sydney / Vancouver / London / US (Demographia ratios), BTC needed for retirement decay curve (4% rule, anchors at year 0/+10/+20/+30), and $10K invested in 2010 — bitcoin vs S&P 500 TR vs NASDAQ-100 TR. Seven charts done; three to go in the final commit 5/30/26 Gallery Commit B: three more charts live. Power Law implied CAGR vs. S&P 500 (with convergence footnote), BTC required to buy the median US house (2013→2025 actual, projected trend to 2032), and the real opportunity cost of buying a house (start-year toggle 2014/2016/2018/2020/2022). Four charts done; six to go 5/30/26 Gallery Chart 1 polish: white historical line now extends to today's live price; hover tooltip shows trend + floor + upper at the hover X (not just nearest); today marker has the radial-gradient halo from the Disciplined Rebalancing chart; editorial prose spans the full chart width for a tighter scroll rhythm between charts 5/30/26 The Gallery rebuilt as a vertical scroll-through of full charts (was a teaser card grid). Chart 1 of 10 live: the Power Law channel in ±2y default view with All-time / Near / Planning toggle. Nine more charts arriving in three follow-up commits 5/30/26 Gallery palette finally rendering correctly (real fix: nested <style> tags in page CSS were breaking the :root variable block). Calculators featured tiles now have matched heights 5/30/26 Calculators page: featured row now leads with The Bitcoin Retirement (with its live mini-preview) — Heatmap moved out, since it's not strictly a calculator and already lives in The Gallery 5/30/26 Gallery polish: page now renders against the proper dark palette (body background + CSS variables were missing on first ship). Calculators page H1 updated to match the nav label 5/30/26 The Gallery is open: 8 chart cards, with the Power Law channel as a live hero and the rest as v1 hand-drawn previews — a visual table-of-contents for the site 5/30/26 Homepage ticker polish: ₿ + price in Bitcoin orange with a slow heartbeat glow 5/30/26 New section: The Gallery — a visual index of charts across the site (placeholder for now; first chart cards land shortly). Nav: Tools renamed to Calculators 5/29/26 Bitcoin Retirement calculator: wider input sliders (3-column grid) now that withdrawal rate is a derived readout, allowing finer-grained dragging 5/29/26 Bitcoin Retirement calculator: withdrawal rate now a derived readout under target income, making the mathematical linkage between the two visible 5/29/26 Bitcoin vs. Real Estate calculator: Power Law scenarios clarified (Upper = cycle peak, ~3× trend) and canonical ? tooltips throughout 5/29/26 Bitcoin vs. Real Estate calculator: Real / Nominal display toggle for projected values, with inflation-aware tooltips 5/29/26 Bitcoin vs. Real Estate calculator: input formatting polish ($/comma/%) and clearer projected-value phrasing with future-date context 5/28/26 Bitcoin vs. Real Estate calculator: cross-session persistence for user inputs + reformed NET headline on retrospective 5/28/26 Bitcoin vs. Real Estate: seesaw chart start-year selector + start-price transparency in comparison table 5/28/26 Bitcoin vs. Real Estate: new Global Affordability Crisis chart (5-market Demographia data, Tokyo case study) 5/28/26 Power Law pages: live BTC price + consistent today-anchor across Disciplined Rebalancing, Bitcoin Retirement, and Borrowing Against Your Stack 5/24/26 Homepage: new What Money Is For exploration added to carousel with silent video intro

What Money Has To Be
A good money must hold across time, move across space, and serve as a shared measurement. These three functions are not a menu — they are structurally coupled. Click through Bitcoin, Gold, USD, and a hyperinflating fiat to see how each holds — or fails to hold — the circuit together.

What Money Is For
Money is for three things: saving, investing, and consuming. Saving is the default state from which the other two become choices. Fiat eliminates the default; sound money restores it. Click through Bitcoin, Gold, USD, and a hyperinflating fiat to see where each money holds — and where each fails — the three jobs.

Bitcoin Spend and Replace
The most common assumption about taxes when spending bitcoin in the US is wrong — but the right version of the practice can reduce the tax on a given transaction to nearly zero. A pragmatic guide to executing "Replace and Spend" cleanly under current US federal law, with the legal background tucked into the footnotes.

The Numbers
Bitcoin and The Power Law
Bitcoin grows proportionally, not exponentially. For every ~13% increase in Bitcoin's age, the trend price doubles. Explore the empirical law governing Bitcoin's scaling — then project it forward against a house purchase, 5 to 20 years out.

The Bitcoin Horizon
Volatility is not risk — they are different categories. Bitcoin behaves the way it does because it is a system being adopted, not an asset being priced. Across fifteen years of price history, no rolling holding period of forty-one months or more has ever ended in nominal loss. Try it against the worst entry points.
