I'm trying to gauge whether $12k is the bottom of this downtrend or not, but apparently it is still fighting and hovering somewhere between $13k and $12k at this very moment. For me, I'd say wait a couple more hours or a day or two before starting to buy. Who knows how far this dip can go? It is already a good buy but again just to be safe, try to weigh whether the market will still slip down or not.
