What would your investment have been worth?
- Bitcoin
- Gold
- Mag 7 stocks
- S&P 500
Silver, crude oil, real estate, Ethereum, Solana and XRP, too. Same money, same dates, one axis — read in plain dollars.
“Same dollars in. Same measure out. The only variable left is the asset.”
The whole idea, in one line
How do you put a house and a Bitcoin on the same axis?
You can't buy a corner of a house each week — but you can measure one. Every contribution buys a fractional unit: dollars ÷ that day's price. Multiply your accumulated units by today's price and you have today's value, always in dollars. The same math runs for Bitcoin, gold, an index and a housing series alike — so they finally share one axis.
Dollars → units → units × the last close → dollars. Nothing here is Bitcoin-specific.
The same $7,100, expressed as the units it actually bought:
What it reads that a plain calculator can't.
Every asset, one axis
Bitcoin against Ethereum, Solana, XRP, gold, silver, crude oil, real estate and the indices — normalized to the same dollars in.
After inflation, not before
Overlay the CPI purchasing-power line and read what your dollars actually kept — not just the nominal number.
Trend & sentiment, in the chart
The Mayer Multiple on Pro, and Fear & Greed on any free account — both drawn right on your DCA curve, not stranded on a separate page.
Weight your buys, then check it
Set a rule — one signal, two thresholds, a multiplier per band — and read it against flat, mechanical buying. The defaults barely move the cost.
Up to five at once
Daily versus monthly, Bitcoin versus Ethereum versus metals versus indices — full strategies side by side on one chart.
The cost of flinching
Model a panic-sell and a later re-buy, and see exactly what it cost versus holding the line. History runs back to 2000.
The highest return isn't the smoothest ride.
| Strategy · $50/mo since 2015 | Return | IRR | Sharpe | Sortino |
|---|---|---|---|---|
| Bitcoin | +4,702% | 60.7% | 0.80 | 1.18 |
| Ethereumsince Nov '17 | +360% | 32.7% | 0.51 | 0.76 |
| S&P 500 | +163% | 15.5% | 2.06 | 3.08 |
| Gold | +150% | 14.7% | 1.87 | 2.93 |
Bitcoin's 60.7% a year scored below gold and the S&P on a risk-adjusted basis, and Ethereum's 32.7% scored lower still, even against Bitcoin over the same years — the exact trade-off Pro's Sharpe and Sortino readouts put a number on, for any strategy you build.

Picture yourself actually using it.
Overlay your state's housing index against Bitcoin and the S&P on the very same dollars, and let the chart settle it.
Real estateTurn on the CPI line and read your gains in real purchasing power, instead of nominal dollars that look bigger than they spend.
InflationSharpe and Sortino score the volatility you actually lived through, so two strategies compare on more than the finish line.
Risk-adjustedSet a buy rule — a signal, two thresholds, a multiplier per band — and the engine measures it against buying the same amount, blindly, every time. Usually it barely moves the cost. Sometimes it makes it worse.
Smart DCAModel selling near the bottom and buying back later, measured precisely against the discipline of simply holding the line.
Trade regretRun five full strategies at once — different assets, cadences and date ranges — and compare them head to head on one axis.
