Burning takes $RUNE out of circulation and stops there. Protocol-Owned Liquidity takes it out of circulation too, and keeps it working. Every block, 20% of THORChain's system income goes into the pool that earned the most fees for its depth over the last 3 days. Arbs pair the RUNE with the token on the other side, so the protocol ends up holding RUNE and $ZEC, $TRX or whatever else swappers want most. That position does three things a burned token can't. -It earns swap fees. -It deepens the pool, so swaps get better prices. -And it buys the dip: when $RUNE drops against the paired token, the position trades part of that token for more RUNE, automatically.
