How should you save data on the number of coins in a clicker?

Question

C++ / C#

Good afternoon!
I recently had the urge to make a clicker (I already did it once, but it was a buggy guan), and I thought about how to store the data on the number of coins collected in the new clicker.

Before that, I used PlayerPrefs.SetInt()from Unity, but I didn’t like it for several reasons: it only works with int and string, and in my clicker the values ​​go far beyond int.MaxValue, and I may store not only numerical values.

Of course, you can make such an economy that 1 unit of this currency is already an achievement.

But I'm worried about how to save the data? If I serialize every click, will it affect performance in any way?

Maybe I'll send all the data to the firebase, but won't it explode (or block me) if each player presses the button 10 times per SEC?

Of course it will.
