1. Whether the company's business scope and business model are reasonable: If the company's business scope and business model seem unreasonable or infeasible, it may be a scam.
2. History and reputation of the company: If the company has a bad history or reputation, it may be a scam.
3. Financial status of the company: If the company's financial status is not good, or there is no open and transparent financial report, it may be a scam.
If you have any doubts or uncertainties about this company, I suggest you do more research and understanding. You can check the company's official website, understand the company's history and reputation, and check the company's financial statements and business model. In addition, you can consult a professional organization or lawyer to help you make a more informed decision.
