The best practices to avoid being unnecessarily scammed are to:
1. avoid falling for too good to be true investment offers
The best weapon against this fraudsters is not to be greedy. Otherwise, you will easily get trap and fall for this gimmick.
2. avoid dealing over the telegram groups
Haven't done any dealings over telegram, and people should think twice about doing it.
3. avoid those who bump into your telegram pm to offer a trade or business deal.
Again, like Discord, telegram is a haven for criminals and scammers.
4. research any investment platform before you invest into it.
Most important part of investing that people really forget. Research and research about the project or product that you are thinking to pour your money. This is one way street, once you deposit then your money is gone.
