If you want to make money, then jewelry wants to make money by cutting gems for others online. If you are not online often, it is of little use. You have mining. If you practice mining yourself, it shouldn't cost much. I feel that the project is still good. There are so many interesting and practical things. Many players want to wash away their skills and practice a new skill. When you really wash them off and replace them with a new one, you may feel that they are not as good as the original skills, and you will regret it and spend money. You can only learn two skills. It doesn't really matter what you learn. I advise you not to wash it off.
