Common trading mistakes on Binance Smart Chain include: transferring to the wrong address, making it difficult to recover due to the unique anonymity of addresses; selecting the wrong currency or unreliable exchanges, which can pose risks; trading at the wrong time, such as selling too early; improper position management, making it hard to track when holding too many tokens; ignoring stop-loss and take-profit strategies, failing to lock in profits or stop losses in a timely manner.
