So when one community has lot of members  but  zero funds yet one has less members and more funds...is this caused by interaction within the community or what ❓

I'm looking at The Bike Truck and Car compared to share it .

The last two are still very new, the last one is mine so I funded it that's why I understand between the last two but the top two...is it caused by less and more Interaction within communities or ❓
