URPD STH
UTXO Realized Price Distribution filtered on Short-Term Holders (<155 days), showing hot money supply per price bucket.
What is it?
URPD STH (UTXO Realized Price Distribution, Short-Term Holders cohort) decomposes BTC supply held by UTXOs younger than 155 days by their cost basis (acquisition price). Each price bucket shows how many BTC were acquired in that range by recent holders. The standard on-chain convention defines STH = UTXOs younger than 155 days, a threshold derived from statistical analysis of spending behaviors. The histogram reveals active accumulation zones of hot money.
How to read
The horizontal axis carries USD price buckets (log scale recommended to capture multi-cycle amplitude). The vertical axis shows supply in BTC per bucket. Dense peaks identify price levels where STH concentrated their acquisitions. The current spot price can be visualised as a vertical marker line: buckets to the left of spot are in unrealised profit, to the right in unrealised loss. Overall shape informs on risk distribution of recent buyers. The Trinity rendering stacks two panels: BTC price on top (log scale + selected-date marker), URPD histogram on bottom with green/red colored bars based on position relative to spot, `% cumulative` line on the inner right axis, vertical spot marker on the X axis, and an on-canvas statistics panel displaying total and profit/loss breakdown.
Key zones
Dense clusters above spot represent underwater STH: strong resistance zones when price revisits them (potential capitulation). Clusters below spot represent STH in profit: support zones when price drops back (likely defense). A histogram strongly skewed toward low buckets is typical of historical bear-market bottoms (STH bought low). A histogram concentrated on very high buckets characterizes late-cycle euphoria.
What to observe
Watch lateral translations of clusters over time (by comparing multiple snapshots): a progressive migration to higher buckets reflects a rotation of buyers with rising cost basis, typical of late bull runs. Conversely, consolidation on low buckets for several months characterizes late bear-market accumulation. Spot vs main cluster asymmetries are the most actionable patterns. To explore this chart in institutional mode : the default **Minimal** mode maximises data legibility (compact stats + period presets 1D/7D/1M/3M/6M/1Y/Now + precise date picker). The **⚙️ Expert** button reveals advanced tools : **🎯 Highlight profit** toggle (dims loss BTC to emphasise the support profit zone), **🔍 Hide outliers** toggle (hides the top 1% extreme spikes to zoom on the main distribution), and the clickable historical events bar with badges (▲ cycle tops, ▼ bottoms, ⚡ macro shocks). The **📊 Compare** button opens a second date picker and renders a delta summary card between the 2 snapshots (supply change, profit zone, top accumulation and top distribution per price bucket). The **📥 Export** button offers PNG (all tiers, with trinityinsights.io watermark + logo + copyright) and CSV (Performance+ only, with traceability metadata : slug, date, spot, mode, locale, generation timestamp). Keyboard shortcuts : A/D navigate dates, W/S toggle BTC↔USD, 1-7 select presets, R returns to latest snapshot, ? opens full help. The X axis carries the **acquisition price (USD)** and the inner right line shows the **% BTC cumulative** (cumulative share of BTC below each price level). The URL retains full state for sharing (`?date=YYYY-MM-DD&w=BTC|USD&expert=1&compare=YYYY-MM-DD`).
Historical context
Past cycles show a recurring signature: at historical bear-market bottoms, URPD STH reconcentrates on low buckets near spot, marking distribution exhaustion. At bull-run tops, URPD STH explodes into high buckets, reflecting late-stage demand. Each halving redraws the cohort by redefining the 155d boundary on new acquisitions.
Expert notes
The STH cohort is inherently more volatile and pro-cyclical than LTH: its clusters translate rapidly with market phases. Reading URPD STH in isolation without comparing to URPD LTH leads to interpretation biases. The correct method is to mentally overlay (or via the urpd-realized-cohort-lth-sth chart) both distributions to see the front line between hot money and conviction.
Common mistakes to avoid
Do not confuse dense buckets with guaranteed support levels: URPD indicates where supply is held, not where it will be defended. A STH cluster above spot can cascade-capitulate if downward pressure persists. Likewise, a large low STH cluster does not guarantee a floor while URPD LTH remains fragmented.
