The only thing that makes sense is either the spike data is inaccurate or this is another exchange heist, maybe someone figured out how to use Bittrex's btc wallet to buy these coins and somehow figured out how to hide it from Bittrex which would explain the volume being absent from the last 24 hour volume info?
Trying not to sound like a conspiracy nut, but this spike makes absolutely no sense.
I'll say it again, I didn't buy up the order book, someone else did who wanted alot of coins. I did see though after he did it was only 1 btc left on the sell book to buy it up 1 btc price, so I went and did it for the lulz mostly, and it was good advertising for XQN. I may be out 200 bucks but hey I know i'll make it up easily with where this coin is going.
