Just finished reading this article: http://mobile.bloomberg.com/news/2014-10-21/bitcoin-miner-ditches-clients-to-chase-2-billion-coding-prize.html

Basically the co-founder of KnC, Sam Cole talks about small-time mining operations becoming obsolete as their profit margins shrink and they get replaced by mega-mining farms. He continues to talk about the $2 billion in btc that will be mined in the next few years and expresses his company's intention to milk as much cash from this cow as possible.

What is interesting to note here is that this guy is measuring the profits in $$$, which is indicative that his company doesn't care for btc and are in it for the potential fiat profits. He doesn't say that there's x amount of BTC up for grabs because he and his investors are only interested in the cash/fiat that can be made from mining BTC. Another thing to note is that he mentions their cost per unit is significantly below $400.

So basically these scumbags have a lot of hashing power, fiat, and probably BTC to manipulate the market.
