I think it's not about how new or old is the projects domain but it's about their credibility. We need to check if the people behind it are real people and then we can proceed about the idea of their project...
And how can you find out when the team wants to remain anonymous? I did not find the team on their official website, which also does not inspire confidence in this project. Actually, most similar projects hide their team, as if they are preparing in advance to turn the project into a scam.
Better to ignore this kind of project, being anonymous means to me that you are not ready for the risk and you want to easily get away if something bad happen in the project.
I usually ignore these kind of project, because if you are confident about your own project then there is no need to hide your identity and you'll be more proud that you've created a good platform just like the top projects today, you can see their founder very vocal and active about their future plans, if the new project doesn't work like this then better to stick to the old projects that are still growing.
