Hopefully this is not mandatory, right? The bittrex addition doesn't play nice with sandboxie (instacrashes) so I'm sticking with the previous wallet version. I'm perfectly fine trading through the website.
Regarding the price, this has happened in the last 12 hours or so:


A second whale accumulated almost 100k coins hence the low price. Once their accumulation is over this will get pumped. It might even happen before the PoW period ending (~37 hours). I think within a week the ATH could reach as high as 20k.
