Ethereum market manipulation happening as we speak?

Decided to check up ETH trading volumes on coinmarketcap and out of the blue, I noticed half a billion in ETH/BTC being traded on an exchange I have never heard of before… Bytex. The ETH/BTC price on the exchange is still at $194 as we speak.

Volume for other pairs on the exchange is absolutely minuscule (, with the next most traded pair being BTC/USD, at a paltry $36K 24hr volume.

My initial thoughts; either it's a group of shorters trying bring the market down or a group trying to accumulate as much as they can before a pump.
