There are many advantages to private blockchains. Advantages include tighter security and less fraudulent activity creating a much more stable investment platform. Since Galaxycoin is an asset based blockchain there is an endless supply of coins based on market demand. This is one of the big advantages over bitcoin. Private blockchains are not private in the sense that they are not accessible by the public. Private blockchains operate more organized with faster processing times and better block rewards and give the public full access to transaction records. Access control is granted based on assigned administrators which helps maintain a blockchain that can be safely tied to real assets.
