Somebody with coins and cash is obviously testing this market. A bit funny that so many of you scream illegal activity when market was selling off and now when it popped on no news or anything, none of you is questioning where all this cash is from.
Whole btc/usd market is in the hands of a few, either its early adopters or some group/individual with cash. Everyone else is playing with lunch money. For this rally to get wings it needs to take out $16.50. Personally I don't think running this market up is their idea right now. Feels like testing to me.
