Well then, I'll try my "luck". I'll see if it was worth it.
An investment in federal treasury bonds would probably be safer and also profitable in the end... Let's see what's left after currency conversion, withholding tax and capital tax...
@Psychorex But be aware that it will take a long time at the end, which is why so few people do it. It's worth waiting, but sometimes it takes ages until the money arrives and everything is finalized. But wish you luck, I can hardly imagine that it will be blocked, so simple money earned. 15% for one year is very good and even after taxes probably still well above bonds but also for more risk
