Ethereum fees are high due to several factors. The high fees on Ethereum are a result of the network's popularity, limited block space, network congestion and the focus on security and decentralization. Ethereum 2.0, a network-wide upgrade aimed at making the blockchain more scalable using PoS, is being developed to address the issue of high fees. This upgrade is expected to improve the scalability of the Ethereum network and potentially reduce fees in the future .
