There is no way economically a pump group would stop after getting this far. I think there will be continued upward movement and stabilization as BLK was very undervalued at 6k-7k sat range. A nice bottom is surely forming, I dont think this was rampant pumping as much as it was hyper accumulation.
I don't like the look of this - from experience when the pumping stops and the space between orders starts to widen, people who bought in at 6000 waiting for more will start to loose patience and cash in.
Expecting it to drop to 10,000 before any further price action upwards.
