We really need a big exchange right now.

Indeed. Once the Android wallet is done it would be good to get some PR (not me, I'm no adman).
Before a wallet is released KHC needs a good block explorer. No big exchange will even look at KHC without an explorer.
Bittrex had a scam coin that ripped people off. They added it without a working block explorer and failed to spot an instamine or a premine. I doubt they will list another coin without a block explorer after being tricked once already.
