Hope you understand now a little better, but i realy advice you to search a german "Steuerberater" as a Specialist for such things. Maybe some of our German Trader can offer you a contact to some who has experience in Bitcoinbusiness. Candoo, 2weix, yxt, Akka or others who have the same tax-problems like you.
PS: i hope my english is not to rusty for understanding, its now over 10 years i dont need it for work anymore.
No I only mistreat other languages manually without Google Translate. You should see my French.
Yes, most likely I will have to talk to a German steuerberater. Hearsay doen´t work. I just hoped that someone here might know of some official statement that would prove the München Steueramt to be wrong. In that case I could spend the Honorar-money on something more amusing
