The coolest thing about RUNE is that you can hold it exclusively while getting exposure to any asset supported by THORChain. I recently minted sBTC on ThorSwap. I paid a 0.02 Rune fee and had exposure to BTC. Rune fell and I burned the sBTC and had more RUNE than I did before.

For people that like to trade and keep money on exchanges... RUNE is that while holding the keys.
