I'm assuming it's a shared wallet that gives the privacy protection?
Our format is unique. All real (not system mixed) deposits to your address are credited. You control your private keys and can sign messages. Your spending comes from different addresses.
What this means is it gives you the privacy of a shared wallet, while allowing you to do things like hold ASICMINER shares to your address.
But you have to have the private keys too if I'm using other BTC when I'm sending?
