The advantage of using a liquidity pool is that it does not require buyers and sellers to decide to exchange two assets at a given price, but instead uses a pre-raised liquidity pool. As long as there is a large enough liquidity pool, even for the most liquid trading pairs, this can make transactions occur with limited slippage.
