MBA is offering you the opportunity to have a swiss bank account that NO ONE knows about.
There is quite a bit of work setting these things up and it does include the need to travel to Switzerland. So it really is quite expensive in time to perform them one at a time. Bundles of 6 or more would be very much appreciated and that is reflected in the fees.
Please note that Swiss Banks keep assets in swiss francs and there is a 1% fee for withdrawal. So you do not want to be withdrawing money from these accounts frequently. They are not meant to be transaction accounts.
Please note. Do not believe what you read about numbered accounts. They are no more anonymous than regular accounts.
Update. I have created a video on the swiss bank accounts opening offer.
