This week's cryptocurrency market overview: oil prices have fallen to a four-year low, risk assets are becoming more attractive, and market sentiment for cryptocurrencies has noticeably warmed. Ethereum has recently performed strongly, with daily trading volume surpassing 1.8 million transactions, reaching a record high, and on-chain activity continues to strengthen. Meanwhile, new blockchain application models are emerging, and the market's expectation index for ecological innovation is rising. The risk-averse sentiment adjustment caused by the recent oil price drop is providing fundamental support for a rebound in crypto assets.
