Hi there,

Crypticpool is in it for the long run, I can assure you that it is not a scam. A new block doesn't get mature (meaning that it show ups as immature balance, you can't send it to any other wallet) until 120 confirmation. The target time is 2.5 minutes per block on average, but sometimes it takes longer. (2.5 minutes x 120 = 300 minutes ~ 5hours) So it will take each new round of unconfirmed earning roughly 5 hours to become confirmed.

Reference: https://github.com/litecoin-project/litecoin/issues/26 (Penguincoin is based on Litecoin)

Right now all the big penguin pools are doing 120 confirmation. Clicks on the links below, scroll down to bottom right and you will see (Note: Round Earnings are not credited until 120 confirms.) on all of them:
