do you think it is a good concept trying to attract potential investors with masternodes?  And how much do a potential investor has to pay for 100000 of your coins to have a masternode ?

Great work! This is a good start to the community as another option that you can get to learn from the Masternode Specialists

Yes, it's better to add information about the team if she did not decide to remain anonymous, this happens and it's not uncommon

Well, that is really true that the team should not only put all the complete information regarding the project only on their website. Because it is really important to have the information here in their ANN Thread. And also, if the Pura project will include their team members profile in public, it will add up a trust towards this project.

Your example, this is perhaps an important argument in order to look at the project, especially now. Probably now is the moment when you can buy coins for a good price.
And the schedule looks really interesting now.

I think there really is not enough information from the developers. Why does the project manager not post here news or updates that occur in the project?

Because this project is not that old and usually new projects need a lot of time for getting into consideration so i think that you should give some more time to the devs and also you can join their social media to get more updates.

The project to be able to achieve success must have a very active team that will response to all concerns and updates us regularly, the developer must assign a community manager to always update the investors and developers about the status of this project.

Well, this is not the only way to segregate their information because there are a lot of sites that can actually be used. As what you can see in the OP, they can be reached through their telegram and other social sites. So, you can have that options for you to be able to know more about the project.
