How Should EBM Be Determined?

[Lightify]

Hello friends. I have developed an Android game and submitted it for review. Since this process will take approximately 1 week, I have prepared the promotional visuals and platforms I will use during this time. I am planning to use Instagram sponsored ads + AdWords. I am considering running AdWords ads for 30 days with a daily budget of 15?, but I am wondering how much I should set the CPC in AdWords. What are the differences between setting it at 0.01? and 0.15?? I would appreciate it if you could provide me with the answers to these questions, as well as the minimum CPC I should set for advertising overseas and for Turkey. Thank you in advance.
