Answer: Stablecoins are designed to maintain a 1:1 ratio with the underlying asset they are pegged to, such as the US Dollar. Therefore, if you deposit 100 USDT via TRC20, you can expect to receive 100 USDT when you withdraw it via BNB Chain. However, it is important to note that the actual exchange rate may vary depending on the fees associated with the transaction and the exchange rate of the stablecoin in question. Additionally, it is important to be aware of the potential risks associated with exchanging stablecoins, such as liquidity, counterparty risk, and market volatility.
