What is their internet connection, fiber? Surely they must have a special contract or multiple providers.
I don't think Bitcoin is a big bandwidth user. A lot of little/small connections.
For an operation like this you'd need, at most, a couple of kilobytes per second. It runs as its own pool. Internally the traffic would be much higher.
Running a wallet with a full block chain would take more bandwidth.
I wonder how much effort they've put into optimisation? Small gains (1-2% rather than order of magnitudes) for these guys obviously mean a lot more than for any bedroom operation.
They're ASIC processors. It's already set in stone (silicon, whatever).

OTOH, every day earlier that you start mining is also worth money. This favors more conservative chip design. Now that conservative 28 nm ASICs are available, they may switch focus to optimizing the design.

That occurred to me while writing the comment, but I assume there are other factors which could be worth monitoring and improving, for example network topologies or even cooling methods.
It's $200k/month worth of Bitcoin . The 'liquidity' we're talking about here is converting Bitcoin into local currency that you can purchase things with.
Again, not a problem.
Possible, perhaps, "not a problem", seems pretty untrue. How exactly would someone go about cashing out $200k worth of bitcoin?
Quite interesting. What's to stop the bitcoin pool from consolidating into a few key players as difficulty to mine progresses? There's no way that the miners are spending >250k/mo and pushing bitcoins back into the system. Wouldn't this hypothetically consolidate wealth in the hands of those with enough capital to create monstrous factories like this?
I wonder about the effects of such establishments on the Bitcoin ecosystem as a whole. In theory, they're supposed to strengthen the network by providing more hashing power. But what worries me is the onset of mega-pools composed of such factories that will gain >51% of the network's computational power effectively gaining a monopoly on Bitcoin.
There is no reason factories like this would WANT to disrupt the Bitcoin network if it's their source of income.. If any organization can get enough hashrate to topple the network, they will lose all that money by toppling the network.
> factories like this would WANT to disrupt the Bitcoin network
You're assuming the people disrupting the network for short term gain are the same as those who made the up front investment into the operation.
This is not true. GHash's past double-spend attack was carried out by a rogue employee. The BGP-hijacking attack which was in the news a few days ago shows another route to a 51% attack. An attacker who can trick a bunch of big miners to mine for him instead of themselves could just as easily have tricked them into performing a doublespend attack.
