Okay, that was clear.
How about the payment for memberships? One times payment? Or need to renew for some specific time?
You just need to hold certain amount of XBASE to be eligible for the Plus, Premium, or Professional Membership.

Hold? It means as long as I hold a certain amount of XBASE I still on one of the memberships ( Plus, Premium, or Professional Membership), automatically? or I need to apply? And the amount that a hold will show in which memberships type we are?
How if someday I lose/uses my XBASE?
