Upgrading to a Premium Team is a smart decision.
Upon upgrading your Team to Premium, all of your Team's existing Projects will be converted to Premium. And every Project within the Premium Team created in the future will also be a Premium Project.

Premium Teams benefit from unlimited Premium Team Projects, as well as the ability for Admins to set Projects to private. Private projects are a very useful tool, allowing the Admin to invite only certain Team Members to the project.
Premium Teams also can have an unlimited number of Team Members, Free Teams have a limit of 10.
