The best way to exchange TRC20 tokens is to use a wallet that supports the token. Sunswap.com is a good option, as it allows users to exchange tokens without having to go through an exchange. However, Poloniex has not supported TRC20 tokens for many days, so users may need to look for other options. Some wallets, such as Trust Wallet, support TRC20 tokens and allow users to exchange them in-app. This is a great option for those who are looking for an easy and secure way to exchange their tokens. Additionally, there are several decentralized exchanges such as Uniswap and PancakeSwap that allow users to trade TRC20 tokens without having to go through an exchange. These platforms are often more secure and provide better liquidity than centralized exchanges.
