People are trading like morons. I hope they shoot themselves in the foot.
Dumping 4.5 bitcoin's worth on the exchange in one go was pretty stupid, but the price will rebound, an awful lot of the trading which you're seeing on bittrex is automatic ping-pong trading, that's why you keep seeing weird amounts or multiples of weird amount that keep fighting to get to the top of the board. I suspect a few people are ping-ponging with 1000+ rootcoins
