Also, about the word "Bank" in our web-service: No we are not a legally registered bank, but then again we are NOT storing or dealing in legal currency, but in Bitcoins. This is an important legal distinction. Also, "The Bank of Bitcoin" is not the name of a legal corporate entity, but the name of a website/web-service; another important legal distinction.
A friend of mine operated a mortgage business with the word "bank" in the name and it cost him a lot of money in legal expenses and he eventually had to change the name. You might want to check into this before continuing with the current name. Best of luck with your business and I wish you the greatest of successes.
