I don't think the market realises that Drk has functional anonymity now.
It had functional anonymity before RC4 and RC3. RC4 is implementation of DS+ improving the set.
RC4 needs to be regression utilized, all scenarios vetted in mainnet, any and all bugs squashed over the next few days. 10s of people put 100s of hours in testnet, so it is upto users to get it going now on mainnet.
I know Evan will never confess to it in the open, but the sneaky release was needed to not give pump and dumpers any chance to manipulate which they did with announcements for RC3 and all other wannabe anon coins.
You will see the buys coming in slowly over the next few days though with media hype, KA's code review and what not. But then again whales may also sneak in anytime they want. You never know what and how they play games.
