Fee Revenue, 7-Day Average smooths daily USD transaction-fee revenue over the last week. It is the faster moving revenue-trend line in this group, so it tracks whether miner fee income has strengthened or weakened over a short horizon rather than on a single day.
A rising series means recent fee support has improved on a weekly basis. A falling series means fee income has softened over the same window. It is most useful with Daily Transaction Fees in USD and the 30-day average, where the question is short-term shift versus more durable trend.
The key distinction is window length. A 7-day average is still responsive to brief bursts in block-space demand, so it can turn faster than the 30-day series without implying a lasting change in the fee market.
