If you want to use a market that forces your privacy,
https://poloniex.com/exchange#btc_clam is the only "real" market atm for CLAMS. Polo has lots of problems going in and out that can cause you to have serious wait times. "They" have given them the fix and are hopefully waiting for them to implement them.
So, something is not right.
