Multiplier Boost are surges to your order fees which better reflect the types of orders you complete and will factor in the distance and effort required for each order. This means that when your order fees are higher, the multiplier boost will increase your overall earnings for that order as well.
So for example, if there's a 1.3x multiplier, an order with a $6 fee will be paid an extra $1.80, but an order with a $8 fee will be paid an extra $2.40. On top of these multiplier boost you'll continue to receive additional incentives offered; announced on our Telegram channel every week.
