I think it would be very helpful if you published some kind of statement regarding your security planning and insurance regarding security attacks.
I am active in the Bitcoin forums and am trying to get some idea of the various exchanges that are in place and what security measures they have taken. I also feel the best way to increase trust is to include an insurance clause in your operations.
It would definitely help attract more customers if you could point to a robust security plan and insurance against losses from security attacks.
