Can any of these solutions (UBS, Credit︂ Suisse, Cantonal banks,...) could be opened on remote? As I know is CIM the only︃ bank that offers remote account opening?
With a deposit over 10M, i am sure things can be arranged.
The plebs will need tax residency or work permit in the country.
Also Swissquote could work within some limitations and can be opened remotely.
