If you buy selling coins mean withdrawing $$'s (or any other currency) to your ordinary real life wallet
there are a few possibilities.

- Most any exchange allows you to move money to your bank account (government can see)
- Use a "giftcard/creditcard" site (not very traceable)
   - www.btcbuy.com
   - www.fastcash4bitcoins.com
   - www.bitinstant.com)
- Buy stuff and have them delivered from any btc shop.
   - www.btczone.com
   - coinabul.com
   - Many more here


These are just a few options but they might give you some pointers.
