The Ethereum (ETH) price in USD kept growing in value over the course of April 2021, at one point reaching over 2,500 U.S. dollars. Much like Bitcoin ( BTC ), the price of ETH went up in 2021 but for different reasons altogether: Ethereum , for instance, hit the news when a digital art piece was sold as the world’s most expensive NFT for over 38,000 ETH – or 69.3 million U.S. dollars. Unlike Bitcoin – of which the price growth was fueled by the IPO of the U.S.’ biggest crypto trader Coinbase – the rally on Ethereum came from technological developments that caused much excitement among traders. First, the so-called “Berlin update” rolled out on the Ethereum network in April 2021, an update meant to pave the way for reduced ETH gas prices – or reduced transaction fees. Second, the arrival of Uniswap V3 in May 2021 – a smart contract protocol - is expected to further optimize Ethereum trading.
