Minimum price the liquidity will be active. If the price goes below this, the liquidity won't be active and will generate no revenues. This will allow to concentrate the liquidity to a price range, thus enhancing the gains. Price is always p = token1 / token0

Range0 <= value

Maximum price the liquidity will be active. If the price goes above this, the liquidity won't be active and will generate no revenues. This will allow to concentrate the liquidity to a price range, thus enhancing the gains. Price is always p = token1 / token0

Range0 <= value
