This is what i keep telling my friends who are just considering getting into the investing business. Nothing's for certain but we can atleast lessen the chances of wasting our time, money and effort if we conduct the sufficient amount of research before investing in "promising" projects.
Yes, what you say is very true, because investing is a high risk thing, so it is very clear that someone prioritizes as much research as possible before making steps to invest in new projects offered by people we don't know.
