So I'm guessing Ethercoin.cc sold out of coin to sale?
...
Actually lots of ethercoin is still for sale at bittrex. Bittrex is the only exchange that i know of that is pre-selling their ether. They're using tokens, i.e., ethercoins, that they are saying will be redeemable one-one for ether. Link to proof of reserves is posted near the beginning of this thread.
