How does something like Adoptables Art for points work?

[michaelmorin]

Hello,
I kind of get the point that you basically make Art of something that is up for sale and if someone wants to buy it they can but how would exchanging it for points work?
I know it's a pretty dumb question but it'd be nice to know.
Any help appreciates

Thanks

I didn't find the right solution from the Internet.
