nobody will ever know.......
BUT check the number of SUPERNODES going online...... it's increasing right?..........
What is the significance of the SuperNodes number online ? Is it the number of users of Nem?
the more supernodes, less and less xems in the exchanges... :-) if you have a supernode, you get a share or get some xems (300-350xem) every 24hours.
I hope this answers your question.
