To analyze the reasons for the decreases in ETH mining revenue, we must first understand the components of ETH mining revenue.
Ethereum reward is divided into two parts: block rewards and transaction fees. A block reward is a fixed value, and transaction fees depend on the network’s transaction volume. The occurrence of a low (or high) income return on a certain day is generally caused by fluctuations in transaction volumes.
After the London upgrade of Ethereum, block rewards remained unchanged but the transaction fee structure was adjusted to “BaseFee+Tips”. Transaction fees are burned and only tips are now allocated to miners. Therefore, this network change may cause drops in overall profit.
Please note that the overall transaction fee obtained by miners is still based on transaction volumes of the network. Even if the fee structure has changed, it may still fluctuate. The estimated reward is a theoretical calculation for reference only. Please refer to the actual rewards from the mining pool.
