First way to avoid getting scammed is to be Skeptical about everything, and unsolicited private messages or DMs should be treated with Skepticism hence if otherwise any dreams sold to you by anyone should not be bought, don't hesitate to leave such conversations that have too much of promise of returns to you.
I hope this helps someone today.
I believe that the first way to avoid getting scammed is not being greedy and believing in something for nothing, secondly not seeking the easy way to achieving a great financial success.
It's better to ask yourself some vital questions or get clarifications on how someone promising you any goodies actually makes his own money from the business. I've learned that for a business to be sustainable, an employer should make up to 5 times or more what he pays for labour or collaboration, so if there's no clear and practical way he gets his own revenue, then you're the revenue.
Greed and lack of understanding are what make people fall into the trap of scammers. When scammers come to this set of people with their sweet stories, at first they never understand that it is just a trap, and they never bother to do research to know how true this can be due to ignorance. All interest is in the offer and how to gain it; because of greed, one can't even afford to let the offer go. I think if people prioritize knowledge, the chances of getting scammed will reduce because knowledge gives direction and also provides one with an understanding of the implications of greed.
