Complaint Against a Service

Winklevoss Bitcoin Trust /

I don’t understand what kind of a company it is.
The description is blurred and unclear. Nothing is understood. A little information is provided.

Most of the links don’t work.
Looks like they use “The Bitcoin ETF” name to attract clients, but have nothing to do with this.

Not clear what their name is, in general. How is it related to the COIN they often mention? It’s not explained.
Who stands behind the company? What’s their portfolio? Do they have profiles in popular social networks?

If yes, then why is it not mentioned on the website? How can I contact them and where are they located? What country, what city?
It seems like the company stopped operating.
