At first i am particular in Roadmap because that is what the future relies so better those are clear,.
Next and the main thing to be particular is the Team behind the projects.
this will prove their truthfulness and their reliabilities .
Anyone can create a roadmap but the problem is that many projects still didn't bother to finish whats written on the roadmap because they already died in the middle of thier run . Others can write a promising road map too but they are only not legit . Same thing can happen on the teams , teams are also popular in terms of manipulation . Not just these but almost any requirements can possibly be fake now , it's hard to believe a true legit project today .
