I've been the GCN/DOGE activity on globalcryptoexchange -- smooth, simple, easy -- perfect really.  It's a plain and simple site -- just need volume -- I threw about 6mil over there to get early sells high in BTC, LTC and DOGE.

Buys and sells work, nice notifications and confirmations on the user side -- gotta assume LTC and BTC are the same.

Copy 'n paste from my transaction history:
