No clue. But from what i have been told all of the majors will be on this.
Also I will call Citi Bank tomorrow.
Citi Bank is in partnership with Warka Bank in Iraq right now,
You can go into Citi bank and open an account and from that account open a Warka bank account and transfer funds to and from your Citi account to your Warka account.
So there is a very good chance that Citi also buys and sells but I will get that info in the am.
I do know people who are connected to Chase and Bank of America people and they both say they are expecting this event and will both exchange when it happens.
