If I'm looking to find a correlation between price and masternode declines, then I can exclude protocol changes, right?
I have statistics for almost everything:
http://178.254.18.153/~pub/DRK_payments_history.pngOrange: DASH per day per Masternode
Blue: Dollar per day per Masternode
Grey: Number of Masternodes / 1000
(not 100% what you wanted, but still quite interesting)
