It can be a good strategy that will also influence your revenue positively. You might want to offer higher value to users based on their geo location, in accordance to the daily rates in our agreement.
For example, if your value offer to all users is 1000 points, or 1 extra character, you might offer 2000 points/2 extra characters to users in a country where your daily rates are higher.
To implement the above, all you need is to identify the user by country or other characteristics of your choice, and modify the benefit text depending on the offer you provide them with.
Remember to apply this benefit after the user give their consent.
