$ETH O Ethereum ($ETH) continues to be one of the most fundamental cryptocurrencies in the blockchain ecosystem. In addition to being the native currency of the Ethereum network, which supports smart contracts and dApps, ETH is also widely used in staking with Ethereum 2.0. I have ETH in my portfolio as a long-term investment and I also use it to pay gas fees in DeFi transactions. Recently, I made an exchange from USDT to ETH aiming for a price appreciation movement following news about improvements in the protocol. The liquidity and global acceptance make ETH an indispensable asset for any crypto investor.
