Sunswap does not offer the ability to purchase ETH directly, but it does offer liquidity on the ETH-USDT TRC20 pair. This means that users can swap their ETH for USDT TRC20 tokens, send them to their TronLink wallet, and then purchase ETH on the dips. By taking advantage of the liquidity offered by Sunswap, users can still purchase ETH without having to go through a centralized exchange.
