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.
