How can I use AI to make money?

Could you possibly elaborate on the methods of leveraging artificial intelligence for financial gain? I'm particularly interested in understanding how AI can assist in trading cryptocurrencies or stocks, or perhaps even in identifying novel investment opportunities. Additionally, are there any specific AI tools or platforms that you would recommend for beginners in this field? Moreover, could you discuss the potential risks and challenges involved in using AI for financial purposes? Finally, do you have any advice for someone looking to start their journey in AI-driven finance?
