Supposedly some hedgefunds on OKcoin jumped in for 3 Billion. Not sure if true but they made the post themselves.
I doubt that's it.
Markets move on technicals, not good news.
If that were true, everyone would be rich what TA predicted this rally?
I can imagine that there are insider news only a few have acess and started to drive the market.
As soon as there is a movement for all notible they jump in and put fuel into the fire.
OKCoin just said they had a new client worth $3 Billion, that's what their other investments (stocks, etc) are worth. That doesn't mean they were going to drop $3B on the market. That news may have fueled the fire a bit, but I can't imagine it being the sole cause either.
