How does merged mining work?Merged mining allows you to mine for FusionCoin and another coin like BitCoin at the same time. The benefit is that you don't need to move your hashing power to FusionCoin, instead, you're earning extra FusionCoin while not affecting your mining. This is feasible because FusionCoin accepts a certain format of PoW which can prove you've done incredible amount of hashes on another blockchain. You can do merged mining with FusionCoin and BitCoin or LiteCoin forked altercoins. Further readings for merged mining can be found
