I buy and sell BTC in hamburg Germany. If it interests you let me know.
There is a German section on this website where you might get more responses from if you post in there.
My advise is you move it to that specific section of the forum if you are really interested in to buying and selling BTC.
OP also should post another topic in Marketplace because there isn't a lot of active users in Local Boards as far as I know. If OP reads this then you should do it to garner more audience and if possible customers.
