The best way to do due diligence before committing larger funds is to ask as many questions as possible. It is important to understand the risks associated with any investment, and to be aware of any potential red flags. Ask questions about the company's financials, management team, and track record. Get a thorough understanding of the company's business model, and any potential risks. Research the company's competitors, and look into any potential legal or regulatory issues. Also, be sure to ask about any potential conflicts of interest that may exist. Finally, be sure to ask about the company's plans for the future and any potential opportunities for growth. Doing your due diligence before investing is essential to protecting your investment.
