Staking here is a pure locking mechanism - it earns no CCT reward. Mining CCT happens through validators instead (see the Validator page). CCT/ETH staked here are test/demo amounts only, with no guaranteed monetary value.
Unstaked balance stays bonded (still counted, still slashable) for a cooldown period before it's actually released back to your CCT/ ETHTEST/USDCTEST balance.
