Apprently bitcoins - which are actually nothing more than bits and bytes on a computer are created by running a computer program called a mining program and apparently bitcoins that are created in this way have value and can be used to buy stuff and to gamble. You can run the mining program on pretty much any computer and every once in a while, out pops a bitcoin. But what it you run the program on a super computer? So now, some clever people are designing very special purpose computers (ASICS) to do the mining. The special custom chips are being manufactured in China - you know - where they make the Apple iPhones and such. Now a bunch of people can't wait to get their hands on these printing presses for digital money, and some people have pre-ordered / pre-paid for these machines and are somewhat patiently waiting for them to be delivered - having paid anywhere from $1,299 to $30,000 - depending on the size of the machine. The $1,299 machine is about the size of Mac Mini (if you remember these) or a Boxxee Box, Roku Box (6 x 6 x 2in), and the $30K machine is about the size of a mini bar fridge. None have actually delivered yet, but one of the three companies says they will be delivering in the next few days. This other company BFL, the company that is the subject of this video, with the black box with fans, said they were going to deliver months ago and people are still waiting.
The interesting thing I found is how the cost of electricity factors into this. You see it takes electricity to run these special computer machines, and they run 7é24 and they run hot and consume a significant amount of electricity. Also, apparently, it gets harder to mine bitcoins, the more mining capacity exists. So there is a formula for determining how profitable / ROI of these machines, based on the initial cost, the cost of electricity per kW hour, and the time it takes to create a new bitcoin.
