$ETH Ethereum (ETH) has recently seen strong momentum, with prices soaring over 40% in the last 72 hours, reaching the $2600 mark, marking the best three-day gain since 2019. The increase is mainly attributed to the following factors: Firstly, on May 7, Ethereum successfully implemented the Pectra upgrade, introducing key technological improvements that enhance the network's usability and flexibility; secondly, there was a large-scale liquidation of short positions in the futures market, creating a 'short squeeze' upward spiral; thirdly, on-chain data shows that 'whale' addresses holding over 10,000 ETH have significantly increased their holdings since late April. Additionally, May is often the best-performing month for ETH, with an average return of 27.36% over the years, and the likelihood of maintaining above $2500 on May 16 is 72%.
