I visited both Bahamas (Atlantis) and Hawaii (Kauai, Big Islands). For me, between the two, I would pick Kauai in terms of livability and for things to do and overall quality of the place. The only sucky thing about HI is the timezone, it is a couple of hours ahead of PST which is already bad as it is for me.
I meant how much does it cost to set up a Trading business so you can get the visa which enables you to trade full time in the bahamas.
