New projects give new opportunities. That is why many investors are interested in new and prospective projects to know about such opportunities and earn money on investment.
This is not always the case that you earn by investing in good companies. Sometimes, new projects investment go in vain if the project turns out to be a scam. No matter how much you research on a new project, there is always a greater risk involved.
If you ask my personal opinion, i would prefer to invest in a project which is already established and trusted by many people. I fear investing in a brand new project.
