The dividend gets written to a new USD account within Swissquote. From there you can invest in VT or VWRD (which is VWRL but in USD, traded in London). You could also probably transfter it out of Swissquote to a regular PostFinance USD account, in order to send the money to another broker. But someone wrote here that it costs money.
To be clear: I’m not looking for some quirky solutions that waste time. It should be simple and minimalist.
