That's my understanding wrong, I'm sorry.
NXT has been diluted due to expenses
VPN is a bit less due to some market making inventory
other coins are very close to the same, you can just compare the totals now against the totals in the past. the coin addresses have always been public
So for the most part the coins inventory is the same, with the small exceptions. Of note is that 18 million IOTA has been acquired, which was not originally there. So, whatever usage of the coins is more than compensated by the IOTA value
