Saw few moment ago 250MH alone on one pool and this was 99% of all the Net hash. This isn't healthy anymore. The pool operators should ban these farms or hobby miners die hard.
this is what happens no matter what the coin is, just have to jump around and find something new until the farms bugger off. we little fish miners will always feed of the scraps of the big farms thats just how it will always be. Althou if the price does not move anymore and drops it will be unprofitable for them and they will leave like always.
Plus i believe is was just a group of people buying in at a low price and thats why the movement has pretty much halted for the moment. if it was a pump the target was not very high so seems unlikely and there is a chance the price will return close to where it was for a little while longer.
