This is quite interesting and the prizes are really good. So every month there are 75 winners? But dont you consider to pick the winners weekly and minimize the prize and the ticket instead? Im thinking its a bit long to wait monthly to know the winners.

This is good. To those who are hesitant to sign up because of the mobile number requirement. There's actually an option to skip it however there's no $50 bonus.
