What does Unlock mean?
You set a minimum guarantee before your release is readable by the public. The Unlock System allows you to set a price that must be met before it is readable by the public. For those that want to read your manga they add Coins to your release. Once the Coins reach the goal your manga becomes public and you get paid. By using this system you can be certain you'll make a set price before the masses can read your manga. Then once it is unlocked you can continue to earn money through the ad revenue system.
