It’s not so easy to identify scams sometimes I would say anything that sounds too good to be true is not real or any investment that promises quick returns or 100% profit is likely to be a scam. Also if an unknown person messages you all of a sudden telling you about an investment that will bring you profit in a short period is also a red flag, so treat any message from any social media platform about a certain investment as scam, never click links from an unknown source, some are been sent via email they are very risky.
There are several red flags we can use to identify scams but ignorance will always make people fall victim to scams sometimes all we have to do is make research online to educate ourselves better. A lot of people will give your information on how to identify scams but i still think you should carry your own research about how to identify scams to widen your knowledge more. A simple search on google would do.
