I am a bit wary of claims of earning “up to 37.55 % p.a.” on my assets.
I saw that you did edit your initial wording from the original post (that I quoted above). 
They are for sure advertising and trading on their “Swissness” - though their legal and contractual structure seems abit convoluted and messy. Especially with regards to Swiss users and their execution-only mandate agreement with the Swiss representative company. And I haven’t even looked into their yield program yet.
But to be fair, they do seem rather upfront and transparent about their legal and holding structure. Especially if you know where exactly in their FAQ to look on their web site.
Compared to many of their peers (see my the discussion on Binance earlier today), they’re also almost a model in transparency in how they’re indicating both their entities with physical addresses on their web site. So to be fair, you have to give them credit for that.
I just wouldn’t consider or present them as a fully (and “transparently”) Swiss operation.
