In my view, if there's a new project out there that you think would be perfect for your investment - do not invest big but instead watch how the project perform first or how the team is doing their best to increase its value and its use-cases - this is why roadmaps are important and should be visible for every traders to see.
Take a look at when the project was established and how it has progressed on the roadmap set out when it started. If they managed to achieve it and the problem that they set out to solve still exits then go ahead with some amount comfortable for you.
