research on the project a hundred times and trace the background of the team behind if they were into successful projects or not, or were also involved from those scam projects in the past. Its better not to invest when you're in doubt, than taking the risk and end up losing your capital.
True, that's what I have been using when tracking projects to support on. Stuff like if they copy the whole team from other projects to theirs or if they have involved on another scam projects back then etc. But, most of the people just blindly choosing the projects because they think the projects look "good" without any valid position and then they cry after that.
Well nowadays many projects really look good to me because the scammer is developing their new way to scam us, every time we know their method to scam they will improve their method too scam us till we fall in their trap. If you can't afford to lose money better to join a trusted project rather than lose your money in vain and forget about quick profits if you really want to join a new project.
