Interpretation Understanding feerate_percentiles_25_usd helps users set realistic transaction fees for non-urgent transactions to avoid overpaying while still having the transaction eventually confirmed. This metric can also indicate the level of competition for block space during lower activity periods on the network. Lower percentile fees may signal less network congestion, potentially correlating with times when demand for transactions is reduced. Conversely, an increase in the 10th percentile could suggest growing network activity and competition for space in Bitcoin blocks.
Advanced Explanation Transaction fees in Bitcoin are measured in satoshis per byte, with high fees typically leading to faster network confirmations. feerate_percentiles_25_usd captures the average lower boundary (10th percentile) of transaction fees for a given day, revealing fee rate benchmarks that 10% of all transactions do not exceed.
