.de is a German site or a Danish site?
.de is Germany, .dk is Danish
But as internet has no many rules and regulations, you can run any extension of domain from any country.
Example, your domain is .ru and your hosting is in UK and you are from Australia.
I've never been buying and selling bitcoins since ive started with them, but now I have to. I've been told by a user here to use
www.bitcoin.de for buying and selling, and I'm having some trouble. Can anyone pm me who has created an account there or successfully bought or sold btc.
You can buy on (example) BTCe, or Poloniex.
I never tested bitcoin.de.
