a sudden dump at 0.000575 then another at 0.000511 that is a huge drop in price imho not somebody panicking ... co'z between 511 - 575 you'd think twice about why not sell at 574 etc... instead a big 511 dump
Those sells didn't happen until the big bids at .63-.64 dropped... that's called panic. If not, and they just wanted to sell why didn't they do it at .64?
Because they are noob traders. Majority of miners have no clue what is the difference between just dumping coin on exchange filling buy orders and putting sell order.
