Golden Finance reports that according to data from Glassnode, the source of income for Bitcoin miners is changing significantly, mainly driven by transaction fees. In early 2024, the proportion of miner revenue that came from transaction fees peaked at nearly 72% in April and then stabilized at a lower level. This change is related to the launch of Runes during the halving, indicating an increase in transaction processing needs. Historical data shows that surges in fee revenue are often associated with price fluctuations or network activity. Recent trends suggest that miners can profit from transaction fees when Bitcoin price and network activity increase, underscoring the critical role of transaction fees in miner revenue. Understanding these trends is important for predicting the financial health of miners and the economics of the network.
