Doesn't change the fact that that positive segwit news/rumors make the price go up and negative segwit news/rumors make the price go down.
When Charlie Lee confirmed that Wang would not stop signaling segwit, price went back again.
Now if Jihan confirms that he will drop that amount of hash rate against segwit, the price will go down too.
Rumors have to contain information and depending on what the rumor says market reacts.
TL;DR: segwit news/rumors make the price go up and negative segwit news/rumors make the price go down. This is a fact.
Speculators always trade off "news", doesn't matter what the news is. And that is what we are seeing.
I actually hope Litecoin does adopt Segwit, because afterwards it will prove no-one uses it and no-one wants it.
