It will take time for you to get your miner, and difficulty might rise during that. Also, please use comments to comment on another answer. I recognize that you can't do that until you have 50 rep, but please wait until then.

<p>There's a factor called Difficulty, the more hashing power exists on the network the more difficulty exists, therefore it's harder to mine coins. Right now The difficulty factor would let you recover your money fast  because almost no one has ASIC chips, when they ship in bulk the difficulty factor will rise to 30-120 million during the year. To know by how much the difficulty will rise it's impossible, so it's your call.</p>

Perhaps they are selling pre-orders and while that's happening using their own hardware to rake in the coins. By the time the hardware ships the difficulty may have racked up making their hardware less valuable but they've double recouped in the meantime (early access to the hardware + sale of the hardware).

The upfront investment in these chips must be pretty big though - still quite a risk for the hardware vendors.

The Bitforce 50GH/s miner costs $2,500 today, and according to the following [calculation](http://tpbitcalc.appspot.com/?difficulty=6695826.2826&hashrate=50000.00&exchangerate=128.06&bitcoinsperblock=25.00&rigcost=2499.00&powerconsumption=80.00&powercost=0.10&investmentperiod=355) it would mine enough coins in about 5 days to pay for itself.

I am sure I am missing something here. Why would they even sell this hardware at all? Surely it makes more sense to keep the hardware and just set it loose on calculating coins and cash them in.

Not if you don't have one already.

The trouble is that you don't know when you'll receive your device and, as @username_8 says, the difficulty will be rising in the meantime.

Butterfly Labs (who manufactures the device you're talking about) has only just started delivering devices, and already has a large number of pre-orders. You probably wouldn't receive your device for at least several months, and there's a possibility the device will never earn enough to pay for itself.

ASICminer did decide to keep the hardware and mine. They're selling shares with intent to payout the dividends from whatever profit is made.

However, Avalon and BFL didn't choose the same path. As to why, some people believe it's far better to "sell the shovel" than "dig for gold". No one knows what the exchange rate or mining difficulty will be in 3 months (things that affect profits for miners, along with electricity), but none of that matters to the hardware companies, since their profit will already be in the bank.

And the increased difficulty is precisely why the machines won't pay for themselves in 5 days. The might if you had one right now, when difficulty is low. But the network hash rate is going to increase by a large factor once all the ASICs have shipped by this summer.

Eventually, your single 50GH/s machine will be unprofitable as new, more efficient technology debuts and the network difficulty continues to climb.
