You only grow Hive chain if you grow the value of the tokens. I have said this since Steem.

It does not matter where a person is from and what their economy in a country is. There is no investment from Hive to anything that is not Hive unless it comes from one of the same in a group.

The answer to any thing Hive is. Create demand for the tokens from an outside source. This means the source has to be built. This finance for building the source needs to come from the chain. Purchase value is needed. Nothing else.
