A theory about volume could have been that it was all the ICO Btc to pump up volume... but it only looks like their are 22 btc that went into the ICO so the volume must be legit I would guess
can you make 30BTC (yobit) + 78BTC (ccex) + 186BTC (trex) = 294BTC volume, with only 22BTC?
I think that a part, some btc from the ico was used for the first spark, maybe they've bought some CYP from the ICO weak hands, and maybe only in yobit, the rest should be legit.
Now we're in many waiting some movement, a pump, and the only things to do is wait monday I guess, or we'll see tomorrow what will happen.
