The configuration method previously released was sent via short messages, so there were limitations on pictures and text, and many friends still couldn't understand it. So now I have added a complete version. This version will be used as the standard in the future.
Let's start with the PC version. The PC version is the same as the web version. At first, I configured it remotely for people, but later I found that it might be a trust issue. Many people were afraid of what I would do, so I just made it public. Everyone can lose less money and increase their winning rate, and that's ok.
