BTC: Captured mempool base fees in USD — Last Actual Capture

Bitcoin Captured mempool base fees in USD — Last Actual Capture was $7,903.38 on 9 Nov 2026 (latest daily value).

Reference USD value of the base fees in one local mempool capture.

Why use it. Compare captured fee amounts on a common dollar scale while reading fee-market changes separately from the quote. How to read it. Each hour/day point is the last actual accepted local capture in that UTC bucket, not a time average or flow. Only genuinely retained prospective capture and quote receipts can contribute; earlier ranges remain empty. A later calculation does not prove that this USD value was published at capture time. Missing or unpriced latest captures stay NULL, including a native zero; an older priced capture never replaces them. A complete empty priced population has zero amounts and bands, but undefined mean/median rates. Period labels describe sampling completion, not transaction confirmation. Read priced/total capture counts, gaps and the original capture, quote-observation, quote-receive, calculation and separate postcommit acknowledgement clocks. The weakest monetary source clock is min(capture, quote observation); it expires after one hour without renewal from page requests. Source admission, actual coverage and latest-hour delivery remain API-owned. Smoothing applies to already priced last-capture observations with its declared warmup and missing-window rules.

Calculation. Use the own Core grouped base-fee/count/vsize evidence with its exact matched entry-age capture clock. Multiply the exact captured fee satoshis by the eligible USD/BTC quote and divide by 100,000,000. Fees exclude local prioritisation deltas and ancestor/package adjustments; they are pending snapshot fees, not fees paid during the period. Pair that actual capture C with the newest eligible immutable Alternative.me BTC/USD quote Q, no more than 15 minutes old. Its response must have been fully received at or before the start of C's recorded second; a later correction cannot reprice that earlier capture. Retain exact original rights, raw-body and quote receipts. This is a dollar reference, not an execution price or historical-known-then series. Exact rational monetary totals/bands precede 40-significant-digit half-even output rounding; independently rounded bands need not add byte-exactly. Core policy vsize is distinct from independently decoded raw transaction vsize. This is one local mempool, not a network census, inclusion forecast or fee recommendation.
