URPD - Realized Price vs Spot Price
Realized price (aggregate cost basis) compared to spot price over time. When spot price is below realized price, the average holder is at a loss - historically a key accumulation zone indicator.
What is it?
URPD classifies each UTXO by its last movement price and aggregates them into a price histogram. The result shows how much BTC has its 'cost basis' at each price level. Thick bars represent zones of high cost concentration - potential support/resistance levels as many holders are psychologically anchored there. It is a 'density map' of the market's acquisition costs.
How to read
The horizontal histogram shows price levels on the y-axis and BTC volume on the x-axis. The thickest bars indicate 'on-chain volume nodes' - levels where lots of BTC are 'stuck.' If price approaches a node from above, it may serve as support (break-even holders refuse to sell at a loss). From below, it may serve as resistance (holders in loss sell to exit at break-even).
Key zones
The 'air gaps' (zones with no or very few BTC) are as important as nodes - price can traverse these zones quickly as few holders are anchored there. The largest volume nodes in the current URPD are at price levels where the most intense trading occurred (typically prolonged range zones).
What to observe
Changes in URPD shape over time are revealing: if a large node 'erodes' (BTC redistributing), it means holders at that level are selling. If a new node forms at a high level, it means much capital is entering at that price - potentially unsustainable if price corrects.
Historical context
URPD showed massive concentration nodes at the $9-10K (2020 range), $30-35K (mid-2021 range), and $16-20K (2022 range) levels. Each of these nodes subsequently acted as significant support during retests. The 'air gaps' above $69K (2021 ATH) and above $73K (2024 ATH) were clearly visible before the breakouts.
Expert notes
URPD is the aggregated version; the CBD Heatmap (tool #132) offers a 2D version with the time dimension. Combine URPD with Elastic Profit Supply to identify nodes representing not just volume but also potential liquidity. URPD nodes are 'polluted' by internal exchange movements, especially at recent price levels.
Common mistakes to avoid
A large node does NOT guarantee support/resistance. It is a concentration zone that creates an increased statistical probability of price reaction, not certainty. Actual behaviour depends on market context, sentiment, and external factors. URPD nodes are attention levels, not automatic decision levels.
