Obviously you are not so familiar with technology (ofcourse there is no problem with that) you consider audio chips graphic chips asics FPGAs x86 Processors as to be completely different things..
Right, I'm not familiar with technology.
They all have things in common they do binary isntructions... their difference is their efficiency per chip at some instructions etc...
Exactly! And mining with the very latest, very best technology is just *barely* efficient enough to be profitable *if* you are lucky.
to transfere 10000 kilos of gold from lets say africa to USA what do you prefere? to order some fancy highspeed Jets that will need like 10 hours to do the delivery (which you have to wait a year to get manufactured and be available to you and cost like 10.000.000 usd ) or to use simple propeled one seat planes that will do the job in lets say 20 days but cost in total 5.000.0000 and are available right now.
Right, now assume those fancy highspeed jets are just *barely* fast enough to get the job done on time. Good luck with the simple planes -- it will *never* work.
I have an ASIC miner that I underclocked about a week ago and finally shut off today because the difficulty has risen to the point that it costs more to power it than the value of the Bitcoins it produces. I've already paid for the miner, I've already waited for it. Those are sunk costs, and it's not even profitable to keep it turned on. This is technology that was designed from the ground up to mine Bitcoins as efficiently as possible about a year ago.
With people using the very latest technology in new designs made from the ground up to mine Bitcoins as efficiently as possible, trying to use anything not purpose built for mining is not even a "knife to a gunfight" idea, it's a "club to a nuclear war" idea.
In about six months, even today's latest and greatest 28nm ASICs designed from the ground up for mining probably won't pay for the power it takes to run them. Even if you got such a miner for free, unless you had a really good way to get cheap power, you would lose money turning it on.
Even your $7 for 1/3 of an ASIC makes no sense. You can get ASICMINER erupter blades for $300 now. They contain 32 ASICs with all the infrastructure needed to connect them. That's less than $10 for an actual ASIC which beats the hell out of $7 for 1/3 of an ASIC. And how can you possibly operate profitably with all the extra stuff not needed for hashing that you have to pay to power when even these ASICs are not, or perhaps just barely, profitable?
This idea is unrealistic by at least one order of magnitude.
