Press always gets something wrong about Bitcoin. This will be Deepceleron razor #19.
"The anonymous creator put 21M of them in the ground, but with each new batch of coins that's unearthed, the program's code automatically makes it harder to solve the next problem, thus timing out the supply."

"real" dollars? Mtgox is
not a wallet.
