They have a good news about burning Vite from trading fees. But I can't understand why they decreased VX rewards for holding Vite? This was just 15% and now only 10%

Because the value of VX is from Dividend Fund. So we want people to do more trading or to do market make. The staking as mining will decrease to 10%, market make as mining will increase to 15%, trading as mining will increase to 65%.
