Yes, the liquidity is very low. For example, I provided 1 ETH and 1600 wHive in this video, and as of today I own about 10% of the entire liquidity pool and thus, collect 10% of the fees with a pretty small investment.
It is necessary to provide both sides in equivalent amounts - I.e. 1 ETH + 1 ETH worth of wHIVE
