Banks in SL?

I've begun to realize that there are at least a couple different banks in Second Life; I recently started an account with Ginko. I'm aware that there's also a Second Life National, or something like that, and was wondering how many other banks there are - Searching for them seems to be impossible. Are there other banks?

I will admit that I haven't been in Second Life at all much. However I've diversified what little lindens I had in about 4 of them.
1. Ginko Financial
2. Meta Bank (now called "My Second Bank"
3. SL Bank.
and 4. Citizen's Bank. (Gone??)

There is also the octagon bank and Midas Bank I believe.

I've chosen to diversify it like this, because I believe it is far more risky proposition to invest money in a virtual bank than in a real bank in real life. As far as I know, There are no rules governing security of client deposits etc.

BTW: Does anyone know what has happened to the Citizen's Bank that was purportedly run by Adam Constantineau? Also, his "world currency exchange" buildings are all gone and the old Citizen's bank ATM locations now seem to contain nothing but floating debris of some SL DataTech advertisement. Has this bank shut down and flown the coop with all the client's Lindens? Thanks for any clarification

citizen bank was sold in whole to someone else i don't know who
they werent interested in continuing the savings/deposit part of the bank
but i did receive my deposit back
that was about two months ago
he said he had a spreadsheet with everyone balances listed
go figure.

Thanks Adz,

How did you go about getting your deposit back? Did they automatically give it back to you or did you need to ask / request for it back? Thanks.
