Channel points for bits

Can you give points to viewers when they donate bits or buy a sub like with channel points?

Earn

Yes, you can create event for cheer and run command e.g. !points add $username 10 or if you want it more dynamic something like !points add $username (math.$bits*10)

Would that mean that you would get 10 points for 1 bit?
And where can I find an overview of the variables that can be used?
(math.$bits*10)

Yes, in that example it means e.g. 1*10 points

Available variables are seen in event creation

Do I have to enter that in the Filter field?

What do you mean by that? Use operation to run command and paste that command I gave you.
