The contract provides liquidity to the PancakeSwap (SSV2 -> BNB pair). To do so, it utilizes 2-3% of the funds received from the taxes.
Liquidity is provided to the reward pool in BNB directly from taxes.
Half of the tokens reserved for liquidity are swapped into BNB, and are then provided as liquidity using the remaining half. The LP tokens received are then locked.
This is beneficial to all traders of the SSV2 token since the increasing liquidity will raise the price floor and make the price more resistant to sudden changes.
