FB Group

Hey guys, hope you're doing good.

Can someone tell me how much FB groups go these days?
I own one that is about music (electronic more percisely) with 8.300 Members and a friend of a friend is interested in it, I'm just not sure how much should I ask for it?
The group is active however, people are posting there everyday, plenty of stuff.
And there are weekly 100 new members joining or so.
If you need any additional information let me know.

Many thanks!

It depends on the subject of the group and the audience it is addressing.
It can get a lot more people trying to activate your group members in order to increase its members even further - but sounds like a good daily growth group
