Ethereum transaction fees have fallen dramatically, now hitting a four-year low. Recent data from The Blocks Data Insights reveals that the 7-day moving average of Ethereum transaction fees dropped to 0.77 on February 15. This decline represents a staggering 70% drop from the previous week when fees stood at 2.57. Such a decrease indicates a significant decline in on-chain activity, prompting investors to reassess their strategies in the Ethereum ecosystem. Lower transaction fees can potentially attract more users and increase network activity over time.
