There are still some pressure from power down from the airdrop (e.g. pending unstake). Its normal since @steem.leo is not their niche. Once they clear out, more updates take place, few more burns ensue, new external listing through SMT switch or SMT peg are planned, LEO can reach parity with Steem.

There is 262.65 Steem per account (346.5M Steem/1.32M accounts). On the other hand, there is 634 LEO per account (2.4M LEO/3785 acounts). Therefore, some distribution should take place to reach in parity with Steem.

Moreover, Steem is three years old and Steemleo in only three month old.
