Is this multipool dump you guys are talking about being automated ? for what amounts does it sell each time then and how often ?
Yes it's automated. If I understand correctly, multipools mine the most profitable altcoins then immediately convert them to BTC then pay them out. I'd say they dump around 10-30k coins at a time, eating up all of the top Buy orders. This artificially deflates the value of the coin because the true value is in it's innovation, something that multipools have no interest in.
