Thank you very much the helpful information.
As an EU citizen I can relatively easily relocate to either Austria or Germany.
It's not a problem if it saves me 150K euros in taxes.
Can you PM me or write here the contact details of said accountants and tax advisors?
Thanks again!
You're welcome. For privacy reasons I won't be sharing my personal tax advisor, but I can refer you to Mag.(FH) Natalie Enzinger:

I don't know her personally, but she's the one that did the tax situation analysis for Bitcoin Austria and appears to have a focus on crypto-currencies.
Good luck out there! Feel free to PM me if you need further information sources that are hard to find for non-German speakers.
Can definitely recommend Natalie Enzinger. There is nobody I know of that has more knowledge regarding the blockchain topic than her. Be careful though, there are other consultants in Austria I would not trust. If you need more information regarding that feel free to contact me via PM.
