                          $Prospective

- Dynamic lp to mc tax - Completely automated algorithm.
 Designed to balance the tax distribution equal to market cap/liquidity ratio,
 called when specific thresholds are passed.

- The dynamic liquidity feature automatically gives a higher LP % as MC rises, and lower LP % as MC lowers.

- Pure $Futura fork!
