If you want to give a fair prize to the campaign participants then you also have to total a large token. Many people will be interested in the project you create. For the percentage data in each campaign, I often see from most of it is:
signature: 40%
facebook: 10%
twitter: 10%
youtube: 20%
translation: 20%
I hope the information I rellase is very useful and apologize if there is a mistake
