I am not sure but I think it takes 3 HIVE to set up a community on Hive.blog. That simply gives one a community which is different from the tribe idea on Hive Engine. On there, we see a cost for both the tribe and the token.

Setting up a community through Hive.blog has no token with it.

Perhaps others can provide more details but that is my understanding.

@khaleelkazi would know better, maybe he will chime in.
