I think before we invest, we need to have a good idea about the project we are going to invest in. If the projector is bad then we will have loss and if the projector is good then we have the possibility of profit so we have to look carefully before investing.
Well doing our own research is always an advise from the expert before investing, this is our own funds and asset so we need to take care of choosing the project that we invest, not just investing without a proper knowing about the project and the team behind it. The most important is to know the project because there are a lot of scams and we will loss if we are not careful.
