you cant be sure of an investment being right or wrong. Investment can go either ways good or bad. That is why it is important you do an extensive research to be sure that the upside over weigh the downside before investing. All investment cant always be right.
Yes. They can't be right all the time but if you chose not to land in a wrong project, you can really do it if you check the transparency of the project particularly the team behind it. If you can go beyond the real identities of the staff and check if they are legit, then you don't have to doubt that the project is not a scam. Sometimes a good project attracts us in the first place but only to find out that we are only lured by it and this is the reason why we should be extra careful in choosing which project to invest.
