By that math it is 7 days x 1756 DVK / day = 12,292 or so coins right now. Is there a site that shows the current total number of coins?

24 hour volume is 16,612.52948052 DVK on Bittrex. So same coins are being bought and sold due to the high price spike I assume. Then 2115.81188802 DVK volume on Poloniex. This makes it very hard to trade right now with such little supply. Most people will probably hold.
