The thing is, he dumped when the price was high. He said he will dump some time ago and now people forgot all about it and the price went up. Together with Bitcoin Cash pumping, he used the momentum and puimped from LTC pool as well, effectively raising the BCH price and making LTC price fall. I am a bit puzzled why Litecoin did not drop as it could (should?). I have a theory about it and perhaps I can make a post about it. I am sure he is connected to Cooinbase and I know this wasn't because he felt like he needs to go out of "his own" coin. He did that for his own profit.
