"Every year a number of reportedly secure systems fall to the skilled hands of security researchers at Defcon. This year, Casascius’ Physical Bitcioins were on that unfortunate list.

  • @CoinGuy, thanks for sharing. That's a very important development for anyone who is looking to purchase the Casascius coin. This just proves again the point that while Bitcoin protocol itself is solid, the actual ecosystem around it is still maturing and has a few holes to plug.

    P.S. I am looking into migrating all my wallets to a hardware-encrypted usb flash drive...
