Cryptopia paused PAC/LTC and PAC/DOGE markets, and someone setup api bot to buy at 1 satoshi and sell at 2 ... Same thing is happening on other small exchanges where is available PAC.
That would explain why the sell wall for 2 hasn't really moved at all. Not a very smart bot, IMO.
Well, somebody is happy with easy way to double BTC

There are also fake 3 satoshi wall which appears and disappears leaving impresion to buyers price will rise ... Simply avoid PAC for now until DOGE and LTC markets are open.
Wish I had a bot doing this and making me BTC. Would've had it start going higher than staying with 2 satoshi, though.
