You should︁ be asking a lawyer these questions. The more detail you reveal, the more it starts︂ to sound like it might be a regulated activity. But if all people do is︃ buy information from you and you make it clear that you're not offering investment advice,︄ it might be fine. It depends on how you phrase things and structure the flow︅ of information. In some jurisdictions, that you do could be construed as investment advice which︆ might require a license, registration, or other approval/supervision action.
