If you log in in your cex.io account you will se in the upper part of the screen that the tos will be effective on 4th feb.

For price down, i'm expecting it, during the previous difficulty jump of 13 Jan the price hasn't done a retarget, so probably someone with huge power or new power injection directly from cex mantained the price higher, now probably this has stopped and the price has to recover two difficulty jumps so is going down....

(This is my opinion, no proofs about that).

Cheers.
