nope, they are in the block chain, even if you are mining them. All it is needed is for some sites like Coinbase or Coindesk to publish their historical prices for BTC. The rest is just a software problem.

Coinbase and Cryptsy are based in the US, I could easily see them doing that and requiring proof of ID. Coinbase is already doing some of that since they are paying out in USD.

You do realize that you can mine to a wallet and transfer to and from that wallet to anywhere in the world. No exchange is needed.

Better, how many hashs can it get on cudaminer?

Good luck getting the coal companies to sell, a railroad owns about 10 percent of the land in West Virginia alone. They are not planning on selling that anytime soon.

and they just had came up with strip mining in the USA. Whole mountaintops in West Virginia were removed along with coal and it was a lot cheaper than underground mining.

decreasing market share? AMD has fully sold out it's entire retail inventory to the point they are talking increasing production to meet demand. AMD numbers are going to be huge.

Does it increase my mining hash speed? If you are buying AMD cards for gaming at today's prices, you are an idiot.

Virginia does it too, works pretty good unless it is a Rain to Snow event. We had about 3 inches here from this storm and it was a little slower on the ride home, but not that much. The trucks are pretty pricey however.

Atlanta very easily could buy a bunch of salt and spreaders, then just pre-treat the roads and they would be fine.

and FBI just happen to take 911 calls from a movie theater? Looks like we have too many FBI agents standing around.

Coinbase is cornering the market on this and others are starting to jump in. There is now a bitcoin ATM on Wall Street.

We have 200+ years of coal reserves in just the US and we are not mining most of it due to environmental reasons. If we start running out of power, those regs will go away.

You put a supply of H2O in Geo-sych and your phone will be ringing off of the hook. A refueling station outside the gravity well is the start of a new space age.

Bitcoin mining, there is a thought. If you can't sell the power back to the utility, dump it over to the miners during the day. They can definitely ramp up and down as needed.
