it means that if we currently (in this eopch) have ~ 3,600 nodes, the number of invitations (theoretically) may reach ~ 1,800, will there be a demand for such a large number? we will see .... on a telegram and discord many people ask about them every day ....
Why theoretically? If the protocol issue 50% of the current nodes of invites this is it. Some are using them and some are not, but the invites are there. BTW I have an invite available for someone interested, just PM me.
