Not a lawyer, but I believe in a lot of countries, minors can’t sign contracts or trade legally without a guardian. Speak to a guardian before doing anything alone, as they know best how to do things properly without getting into legal trouble.
like what @Dark Dimension said you should ask your guardian, because I don't think just using their bank info is enough since you would also need tax info and your guardian probably needs to look into some legal precautions.
