my 2 cents. we have a large holder exiting or that has finished exiting. the large sell walls are a much bigger dash whale keeping the price in check and forcing the dumper to liquidate at low prices, the large buy walls were probably pulled for the same reason. pretty smart imo, either way the walls are there to protect new and old dash investors alike. that's my "the glass is half full" view, but i have not had much sleep the last few days and probably have no idea what i am talking about, goodnight.
