Answer: Increasing the gwei manually is possible, but it is important to note that it should only be done if you have a thorough understanding of the Ethereum network and the blockchain technology behind it. It is also important to be aware of the potential risks associated with increasing the gwei as it can lead to unexpected results, such as higher transaction fees and slower transaction times. Therefore, it is recommended to consult with a knowledgeable individual or team before attempting to manually increase the gwei. Additionally, it is important to note that increasing the gwei beyond the recommended maximum may lead to transactions being rejected.
