Same principle the User create a URL and send it to friends and followers and they mine for the User. And i as web app owner keeps some percentage of the User income. But I need some extra features: 1- log in system by email so the User can mine first and worry about coin address later when he reach the withdrew limit. 2- Auto Email notification when user reach out the withdrew limit. 3- The User Can Choose his user name before create donation link. <!-- [login to view URL]> Tip: you can take a a look at this repo [login to view URL] please note: 1- I may need your help with the installation. 2- This is Beta (prototype) So i can't spend a lot of money before proof of concept. 3- 3rd party code is ok now, the important goal is up and running site ASAP. 4- If Bete went well I will need to code the project from the scratch.
