Coins is a virtual currency that can be used to subscribe to the locked chapters on Fasynovel, equivalent to Gems.
However, after Coins is transferred to your account, it is valid for 30 days. Please use within the valid period.
If your Coins is sufficient to subscribe to your selected locked chapters, Coins will be deducted first; if not, your Gems will be deducted instead.
A single chapter doesn't support to use Gems and Coins simultaneously.
