Bitcoin Investor Tool — 2-Year MA Multiplier
The one chart to keep: price against its 2-year average and five times it.
Historically, buying below the green line and de-risking above the red one has framed every cycle. Descriptive, not advice. Drag to zoom · double-click resets
Bitcoin: 365 Day Moving Average
Price against the year behind it, and every time it climbed back through.
Price crossed back above the average 9 times in this window — computed from the two series, never drawn on. Drag to zoom · double-click resets
200-Week MA Heatmap
Monthly dots coloured by how fast the long floor is rising.
Dots run cool (purple, slow 200WMA growth — historically accumulation) to hot (red, fast growth — historically overheated); the scale on the right reads them. The 200-week average itself has never printed a lower cycle low.
Stock-to-Flow
Scarcity model vs reality, price coloured by halving distance.
PlanB's scarcity model (0.4 × S2F³, smoothed): each halving doubles stock-to-flow and steps the model up. Dot colour is days to the next halving — the scale on the right. The model has badly overshot since 2021 — shown as history, not endorsement.
Halving cycles
Price across every epoch — the four halvings that happened, and the next two already on the clock. The countdown runs on live blocks.

BTC market cap
Daily close × the supply the issuance schedule says existed that day — computed in-app, no feed to go down.
Bitcoin, in candles
Every close since 2010 on a log axis, where each power of ten is a line the price had to break — lit up to the candle it broke in.
Long Term Power Law
Log price over log time — the straight line bitcoin has grown along.
Log price against log time since genesis — growth has hugged a straight power law for its whole life. The corridor is the fit ± one and two standard deviations. A regularity, not a promise.
Logarithmic growth corridor
The floor, the ceiling, and where in between this price sits.
Both bounds are fitted to our own history, not borrowed: the 1st and 99th percentile curves, which have held 98% of every daily close. The floor is steeper than the ceiling, so the corridor keeps narrowing. Drag to zoom · double-click resets
Mayer Multiple Price Bands
Coloured zones at multiples of the 200-day average, bitbo-style.
Where the 21 million live
Estimated distribution of all bitcoin — and what's still unmined.
Hover a segment. Sizes are public estimates; “left to mine” is live from the block height.
Open liquidity map
Estimated liquidation clusters above and below the market, from our own price history.
An ESTIMATE computed from our own cached daily closes: positions assumed at each close over the lookback at 10×/25×/50×/100× leverage, liquidation levels projected and burned once price sweeps them. Brightness is the cluster's relative weight — nobody outside an exchange sees real positions.

Mayer Multiple
Price relative to its own 200-day moving average.
Price ÷ 200-day average, the line coloured by its own value — the scale on the right reads it. ×1.0 = at trend; above ×2.4 has historically been stretched.
Fear & Greed
The whole index since 2018, and the price it was reading.
alternative.me Fear & Greed index — red is fear, green is greed, the line coloured by the reading. Extremes have historically been turning points.
MVRV — market value to realized value
What the market says the coins are worth, over what they last moved for.
Under 1 the network as a whole is holding at a loss. Above 3.7 has marked every cycle top so far — four data points, not a law. Drag to zoom · double-click resets
Net unrealized profit / loss
The share of the market cap that is profit nobody has taken yet.
Below zero the network is underwater in aggregate. The named zones are the conventional reading, not a schedule. Drag to zoom · double-click resets
SOPR — spent output profit ratio
Coins that moved yesterday, valued at what they last moved for.
One is break-even: coins spent at exactly what they cost. In a bull market the line tends to bounce off it; in a bear market it tends to be rejected by it. Drag to zoom · double-click resets
Puell multiple
What miners earned today, against their own yearly average.
Miners sell to pay for power. When issuance is worth a fraction of its yearly average they are under pressure — which has coincided with the deepest lows. Drag to zoom · double-click resets
Supply in profit
The share of all mined coins that last moved below today's price.
Near a hundred percent nobody is underwater — and nobody is left holding the loss that usually precedes a floor. Drag to zoom · double-click resets
Realized price — what the network paid
The average price every coin last moved at, against today's market.
Realized price is the network's aggregate cost basis. The market has closed below it only in the deepest part of each bear market. Drag to zoom · double-click resets
