The second-largest cryptocurrency briefly climbed to $4,087, testing its recent highs ($4,087) on Wednesday before sliding below the previous day’s open of $4,008. Trading at $3,955 on Wednesday, ETH price has sustained a 2.5% drop in the last 24 hours. Its trading volume is down 20% in the same period, hinting at declining interest among traders. With a market cap of $477 billion, Ethereum comfortably sits in the second position below Bitcoin’s $1.4 trillion cap.
