What are the secret acheivements and how to track them?

Question

I've got a couple of little bonuses of gold at some random occasions when I got things like 100 victories or so.

Thing is, it's written nowhere what are those acheivements are and at how much % they are completed.

Is there any way to know what are those "acheivements" are and track the completion of them?
