ETHLend will allocate 20% of collected fees to purchase LEND from these exchanges to reward active lenders and borrowers to increase user adoption and lending volumes starting Q1 2018.
50% is allocated to active borrowers based on volume and the other 50% is allocated to active lenders based on volume. Rewards can be claimed 30 days after the Q ends.
Why they just not burn this re-buy tokens? Like this made Binance with their tokens for example. It may increase token value.
