Sooo... does the amount you have staking affect the percentage of anon transactions you process? How does it work?
That I don't know. Things will be much more clear in a couple days (beta testing is about to start).
All I can say is this. True anon is generally considered to be impossible or very complicated to achieve. Logically, this means work, and a lot of it, before an anon system has real value. The core Dark team is several people strong, with a dozen more helping with testing and other work. They have been working hard for months. This means the system being built is robust, and will continue to become more so. I do not believe there is a quick solution to anonymising transactions.
