If you want to start with the forex markets than I would prefer you to contact any of the forex broker and follow his signals for first few initial days until you get to know the basics of the forex markets. Brokers might charge you some fees but you would not have much risk over there being with a broker because that individual will guide you from top to bottom of the forex trading markets.

Moreover, I am not sure if we have any such forex traders here as most of the people related here are linked to decentralized cryptocurrency trading which is not similar to forex trading markets. You can find some stocks to invest for a long time considering the demand for the firm behind the stock like Tesla, Microsoft, etc which might give you good profits but yet, you need to find a entry price for those stocks which you could be guided by a broker.
