Cachecoin or Fuguecoin seems profitable to me. There was some underdogs too of course if you subscribe yourself to holynerdvana.com. That guy has a lot of experiences regarding crypto.

Btw, I remembered these days when earning 0.5 BTC daily is easy task. But now everyone rushes in so expecting it will become much harder to earn money with crypto. Esp. if the new 100Mhs ASICs in next 6 months. Scrypt coins will be bullied to death with those monsters.
