Cryptonote Based Altcoin All Transactions Locked
In Bitcoin block rewards cannot be spent until they have become "mature". This happens once 100 blocks are mined on top of a block. The idea is that new bitcoins should not be spread around while they may still become invalid due to reorganizations.

In Monero the maturity depth is 60 blocks, which is reached after about two hours. I assume that Cryptonote has a similar delay for block rewards to become spendable.
