1) You CANNOT advise, trade, manage, or otherwise influence investments without being a Registered Investment Adviser. (RIA) . In the US, the regulations are established by both the SEC, FINRA and each state. RIA’s are licensed by each state pursuant to their “blue sky” laws. In most cases you will find that you will have to have a Series 7 and/or 63 license from FINRA and an RIA from the state if you are acting as an investment adviser. You will have to file a registration statement ADV-2 which is available for public inspection. ( see
SEC.gov | Form ADV).

2) As a general legal matter, when you take someone else’s money to invest, you assume fiduciary duties. That means you are required to act in the investor’s interest rather than your own. The precise details will differ by jurisdiction, but adhering to that principle covers a lot of the potential issues.
