@afstand and @Strabor I hear and read you.
Still, the most trustworthy information at this point comes from the articles of MP and the Poor Swiss. I feel these two articles are well researched and written with certain standards that come close to journalism.
On the other hand, I have not (yet) found an article with a similarly trustworthy degree that claims the opposite and recommends against investing in US assets. Similarly, I also have no knowledge of an experience or an article that quotes a Swiss example of USD 10’000 fees for lawyers, complex processes and year long waiting period.
These two factors, the high quality articles of MP and the Poor Swiss as well as the absence of testimonials or articles about the actual difficulty of getting assets back from IB, make me still trust that US ETFs and IB are a safe bet with one of the best possible performance.
