Brief Description: The highest fee rate paid for Bitcoin transactions per byte.
Metric variants
- _usd: feerate_max denominated in USD.
- _btc: feerate_max denominated in BTC.
Interpretation The feerate_max metric is instrumental in understanding user behavior, particularly during times of network congestion. A higher feerate_max value signifies increased willingness among users to pay premium fees, indicating a surge in demand for transaction processing or urgency among transactors. Conversely, lower values suggest a relaxed transaction environment.
Advanced Explanation In Bitcoin, transaction fees are calculated in satoshis (the smallest Bitcoin unit) per byte of transaction data. Therefore, the feerate_max quantifies the maximum amount of satoshis users are willing to pay per byte to expedite their transactions within a 24-hour period. In this metric feerate_max is converted to US dollars. This addressing of "fee per byte" helps ensure that transactions of varying sizes are evaluated equitably, providing clarity on network fee trends without the complexity of varying transaction sizes diluting the insight.. This maximum value serves as an indicator of the highest payer's willingness to expedite transactions, especially during periods of high network congestion.
Aggregation logic: average over time period.
