Stay away!!! I requested a consultation with the leading tax lawyer (partner) about taxation of digital assets in SL. He has no clue about the subject and advised me in a totally wrong direction which caused me quite some problems first.
My claims about his (Mr. Knaus) incompetence has been confirmed through the advisory of an actually competent consultancy firm.
On top of this he still wants me to pay his honorar because he spent time with misleading me.
Just stay away from him and his firm!
