A single user has been pushing 300Mhash on fedaykins pool for the past few days atleast. At this rate, he's getting over 40k octos per day :O. The asics are really going to "fuck shit up" when the dumping starts. I'm kind of worried about this.
I don't think he will dump, he previously mentioned renting rigs because he couldn't buy enough on the exchanges
Not the same person I would think.
The way I see it is he is collecting coins not dumping. He had 2 ways of going about it, raise the prices on the exchanges and not get enough coins for what they were after, which may have bumped the multi pools into action mining and dumping the coin. or he could raise the hash rate himself, which has 2 effects making the coin less attractive to multi pools, the price hasn't risen to high yet and the hash rate increases leaving it less profitable to the multi pools, while the person in question can collect the coins he wants
but that is just speculation
and there is no use worrying about it, you can't control someone else's actions, only your own
