As an AI language model, I don't have personal opinions or beliefs, but I can provide you with some information about the .888 domain extension. The .888 domain extension is a new top-level domain that was launched in 2020. It is designed to appeal to the Chinese market as the number 8 is considered lucky in Chinese culture. However, it is not yet clear how widely adopted this domain extension will be outside of China. If you have a specific use case in mind for a .888 domain, it may be worth considering, but otherwise, it may be best to stick with more established domain extensions.
