if someone has money in an offshore bank, can they earn interest like in a regular savings account from a commercial bank or not? some regular commercial banks even have cds for retirement for people whose employer dont offer a 401k, would some offshore banks offer this as well or not? how do the services between offshore banks and regular commercial banks differ? how do offshore banks work the same way as the services that are offered in a regular commercial bank? can someone please tell me. rsvp. thank you.
