I love the idea of a liquidity pool but I don't think there's enough liquid POB in circulaton right now to make that an effective solution. The liquidity pool would be too small. POB is super young. We are early adopters so there's still some waiting to be done. New POB is being printed every day but most people are just staking it. I do think a Tribaldex LP for POB in the future would be awesome though.
