Practitioner tool: mechanically clean, but validated only by eyeballing ~3 cycles — no formal out-of-sample test
ORIGINATED BY David Puell (2019)
*Follow the money to where new coins are born. Every block, the network mints fresh bitcoin and hands them to the miners who secured it — the one continuous stream of forced selling in the whole system. Miners have electricity bills, machines to service, payroll in fiat. When the dollar value of that daily issuance suddenly towers over its own yearly average, someone has been paid extravagantly* to keep mining — and history says that generosity tends to arrive near the top. When it collapses below trend, miners bleed, rigs switch off, and the market has often been closer to a floor than it felt.
The Puell Multiple, published by David Puell in 2019, looks at Bitcoin from the supply side — the sell pressure that never stops. Most on-chain indicators study holders and speculators: what the demand side is doing with coins it already owns. Puell instead watches the faucet. Miners are the marginal, structural sellers of Bitcoin: they receive newly issued coins every block and, because their costs are denominated in fiat, they must convert a large fraction of that issuance to dollars to stay solvent. The value of that daily issuance is therefore a clean proxy for the baseline seller pressure the market has to absorb.
The trick is to measure that pressure relative to its own recent norm rather than in absolute terms. Daily issuance value in dollars is just (coins mined per day) times (price). Dividing today's figure by its own 365-day moving average strips out the slow drift of price and the block-subsidy schedule, leaving a dimensionless ratio centred loosely around 1. A reading of 1 means miners are earning roughly their trailing-year average. A reading of 4 means they are earning four times that — a windfall. A reading of 0.3 means they are earning less than a third of it — a famine. (These figures are illustrative, not calibrated thresholds — see the critique.)
The intuition for why the extremes matter runs through price and psychology. Issuance value spikes when price spikes: the coin count per day is fixed by the protocol, so a vertical move in price drops straight into miner revenue and lifts the multiple. Extreme highs therefore tend to coincide with the euphoric, over-extended conditions that mark cycle tops — the indicator is partly reading price back to you, but framed as 'miners are being paid absurdly well right now.' Extreme lows describe the opposite: revenue so far below trend that higher-cost miners capitulate, switch off, and sell inventory to survive. That forced liquidation has historically clustered near the point of maximum pain — cycle bottoms.
So the reading is deliberately simple: high Puell (miners earning far above their yearly norm) has historically appeared near tops; very low Puell (miner capitulation) has historically appeared near bottoms. It is a supply-side companion to demand-side gauges like MVRV or NUPL — a second, largely independent lens on the same cycle. Its virtue is honesty of construction: there is no fitted curve, no free parameter tuned to make the past look tidy beyond the choice of a 365-day window. What you see is arithmetic on two public quantities.
THE MATHS
Puell = (issuance_usd_today) / MA365(issuance_usd) where issuance_usd = coins_mined_per_day × price_usd (coins_mined_per_day = block_subsidy × ~144 blocks/day)

THE HONEST READ · LIMITATIONS
Where this indicator lies to you.
The Puell Multiple has never been subjected to a formal, out-of-sample test. It was proposed in 2019 and 'validated' the way most on-chain indicators are validated: by drawing the line over the existing price history and observing that its peaks and troughs sit near the tops and bottoms we already knew about. That is hindsight, not prediction. With only three or four completed cycles of Bitcoin to look at, the effective sample size for 'the multiple called the top' is a single-digit number of events. Any threshold you might quote — 'above 4 is a top, below 0.5 is a bottom' — is a curve drawn to fit those few points, and there is no statistical basis for trusting it to hold on the next cycle. Treat any hard band as an anecdote, not an estimate.
There is also a circularity worth naming plainly. Because issuance value is (fixed coin count) × price, the numerator is dominated by price on any given day, while the denominator is a slow-moving yearly average. The multiple is therefore, to a large degree, price relative to its own trailing-year trend dressed in mining language. That is not worthless — it is a legitimate momentum/mean-reversion signal — but it means the Puell Multiple is far less independent of price than its 'supply-side' framing implies. It is not telling you something orthogonal to the price chart; it is telling you a transform of the price chart.
Finally, the halving problem. Every four years the block subsidy is cut in half, instantly halving coins-mined-per-day and stepping issuance value down. The 365-day moving average smooths this shock over a year, but it does not neutralise it: in the months straddling a halving the denominator is contaminated by pre-halving issuance, biasing the multiple downward for a stretch. As the subsidy shrinks toward zero and transaction fees become the dominant share of miner revenue, the whole construction — which counts only issuance value — will describe an ever-smaller slice of what miners actually earn and sell. The indicator's meaning is not stable across Bitcoin's own monetary schedule.
