Hmm... You will hate me for saying this, but probably he realized that we are going deeper under ground and he has a lot unsold coins, so he pushed the BTC up, then he will sell the coins at higher price and after that he will let the price go down.
It's possible that it's the same person who put those $104 and $120 walls, probably majority of his coins is in that range.
And what is he going to do when he sell us his coins?
Probably he will remove the walls and give us a few downward pushes, it's profitable for him sitting on fiat at that moment.
I have no idea, but would have thought that this ostensibly lame downturn might be a tactic to make sure enough people sell in anticipation of a fall, so that there's more people ready to buy his coins after he drops the price significantly?
