I live in Germany, so Im no native speaker. Shoot me a pm with the spelling misstakes and ill fix those.
In that case you are of course aware that providing no contact information/full "Impressum" for your "business" is illegal under German legislation. Your website is a perfect opportunity for an Abmahnanwalt to sue the fuck out of you.
EDIT: Oooh, I see that you do know:
I wont provide any informations nor an "impressum" (thats the imprint you were talking about) because the German jurisdiction is insane
Yeah, that must be it. Insanity.
I checked that, he is not hosting in germany. so it may not apply, and since he decided to stay completely anonymous the "Abmahnanwalt" would have a hard time and no easy money.
But since he is offering a high risk venture with "online-reputation" based on some sales, he will probably decide to vanish some time. They all denied it, they all did get away with someones bitcoins...
