build a web coin

We require a new digital currency (serving as a bonus point) that is developed as a plugin to be installed in wordpress platform where users can transact this currency in large or small units to one another from their dashboard. Requirement: * currency name can be edited from the admin panel E.g. 170 "Bonus point" or 170 "Webcoin" or 170 "reward bonus" * currency will not be connected to blockchain. it's not a decentralized global coin, its more like a members' rewarding or bonus point. * value of internal currency (or bonus point) can be set manually in admin panel for users to know the worth when redeemed for a real price. E.g 170 "webcoin" = $0.056 * More Currency or bonus point can be purchased by users * Currency or bonus point can be offered for free (by admin) * Currency or bonus point can be set to automatically increase daily (by a specified percentage) in value for some period of days or time. E.g. 24 hours: 170 webcoin += $0.05 48 hours: 170 webcoin = $0.1 etc * Currency or bonus point can be set to increase by a certain percentage based on the number of user holding it. E.g. 1 user: 170 webcoin += $0.00003 2 users: 170 webcoin = $0.00006 * Currency is not real (It is a bonus point) and cannot be used outside the website but only for redemption on members achievement. * Currency provision is unlimited as bonus point that can be manually or automatically sent to multiple user as a reward to be redeemed
