Looks like a lot of those unexchanged are selling. Gonna be a heck of a payday today!
My unexchanged over three different addresses are basically the same or higher than they were yesterday so it's not that.
Look at the main graph. We saw a large dip in unexchanged and a large spike in exchanged at the same time. I'm seeing this similar activity on all of my accounts.
...but what I don't understand is how the unexchanged rose vertically some 30 (??) minute later back to almost the same level...
If you're talking about the differential right at/near the last payout, it was commented by a few people that that time period correlated with an outage on Cryptsy. I would assume then that the unexchanged pricing data is pulled from there. When the Cryptsy site came back up, the value was then definable again. I'm guessing an exchange happened at the same time Cryptsy came back up to explain the spike in BTC after the payout.
Just some assumptions based on other posts here.
