Well, actually you were right to recommend that he invest while he still has a job. In fact, I also thought like that, and at that time I was forced to invest. However, when I lost my job, I really felt the benefits of the investment. However, this could be a lesson for him that while he still has income, he needs to think about what things are good to invest in and not be quickly satisfied with his income at that time. Investments will help us when we have no source of income. Currently he has no source of income, and wants to invest in bitcoin which has quite a high risk of investing if you don't have a source of income. I suggest looking for income first, because I still adhere to the principle that don't invest using money you don't want to lose.
