I'd love to point out that the amount of hardware required to completely obliterate the security of the bitcoin network, hijack the block chain, etc. etc. is easily within reach of any considerable competitor or prospective "enemy" of bitcoin (governments, paypal, mastercard/visa, banks, etc.).
I bet AMD would be very happy to sell their cards to all sides of the battle in unlimited quantities
. And except of dozens of cards you will need MBs, RAM, CPU, really lot of power (up to dedicated HVAC line), really decent cooling (and it's very expensive) and actually this will be one of the a best supercomputers ever. And overall installation would be fairly expensive, maybe several hundreds of M$ or even more. I doubt bitcoin makes someone lose so many money so it would be a negative profit. Except for AMD who would report a really good quarter
.
P.S. maybe I can have unban? Actually I want to thank Con for his miner, ask question about cgminer and damned AMD/ATI bugz and report couple of bugs/annoyances into cgminer thread since I spent 2 days hunting bugs without success. So I have a question about all those AMD things vs miner program.
