The Hive blockchain has always been a general blockchain that allows for the building of secondary tokens. This means that the entire Hive ecosystem can support a huge amount of value through seperate experiences. In this way, it is similar to eth. However, as you can see with eth, it was unable to scale (might be different with London) and struggled to handle even low levels of volume. I don't know why anyone would build high transaction apps on eth considering the cost of transactions, even if it is a very low cost.
The cost of transactions on Hive is in Resource Credits, which are inky generated through Hive Power. This means thay as the transactions increase, RCs will have a value too and to have them, apps or users will need HP.
Edit:
Splinterlands currently has a market cap well over 100M.
