LTH Supply tracks how much long-term holder distribution is happening relative to its own historical norm, expressed as a Z-Score. Heavy distribution well above normal has coincided with major cycle tops, including April 2021; unusually low distribution — supply concentrating in long-term hands — has historically appeared near and after major bear-market lows.
What Is LTH Supply?
Long-term holders (coins held roughly 155+ days, the same threshold used in STH-MVRV and LTH-MVRV) are widely considered Bitcoin's more conviction-driven, less reactive holder base. Tracking how the total supply held by this cohort changes over time — growing as holders accumulate and refuse to sell, shrinking as they distribute — gives a real, on-chain-verifiable read on the market's deepest layer of conviction.
Accumulation vs. Distribution
When long-term holder supply is growing, it means coins are crossing into long-term status faster than long-term holders are selling — net accumulation. When it's shrinking, long-term holders are selling faster than new coins are aging into that cohort — net distribution. Because long-term holders have already weathered significant volatility to reach that status, meaningful distribution from this specific group carries more behavioural weight than ordinary short-term trading activity.
Why It's a Z-Score
Rather than tracking raw LTH supply directly, this indicator measures how far current distribution activity sits from its own historical average, in standard-deviation terms — a Z-Score. This standardization matters for the same reason it matters in MVRV Z-Score: raw supply figures naturally shift as Bitcoin's overall market matures, so comparing against a fixed historical baseline would eventually lose meaning. A Z-Score keeps the signal comparable across different points in Bitcoin's history.
Reading the Zones
| LTH Supply Z-Score | Zone | Historical Interpretation |
|---|---|---|
| Below −1 | Deep Value | Distribution well below normal — supply unusually concentrated in long-term hands, often near/after bear-market lows |
| −1 to −0.7 | Fair Value | Normal historical range, no extreme signal |
| −0.7 to −0.3 | Elevated | Meaningful distribution underway relative to average — worth watching for a broader topping process |
| Above −0.3 | High Risk | Heavy distribution relative to historical norm — coincided with major cycle tops, including April 2021 |

Limitations
The 155-day threshold is a statistical approximation. Like other holder-cohort metrics, the exact age boundary is a useful, data-derived cutoff rather than a precise behavioural line.
Distribution isn't inherently bearish. Long-term holders selling into strength during a healthy bull market is a normal, expected part of the cycle — the signal is about the degree of distribution relative to history, not distribution's mere presence.
It's a slow-moving, structural metric. Because it tracks a supply-wide cohort shift, it changes gradually and isn't well-suited to short-term timing.
How to Use It
LTH Supply is most useful as a late-cycle warning gauge — when it moves deep into distribution territory alongside other cycle-top signals like elevated RHODL Ratio or STH-MVRV, that agreement adds real weight. It's also a useful accumulation-phase confirmation tool: sustained low distribution readings alongside favourable valuation indicators is a genuinely reassuring combination.
It's also one of the 21 inputs to our Cycle Compass composite score.
