Commissions are killing my bot (Any 40% ref?)

I have created a small trading bot for Binance, the idea is similar to market making => trading on quite a small spread with high volume of small trades. Some examples: https://imgur.com/a/eUTV3l6

(Have overall trading volume of more than 30 btc a month). But I am really struggling with such high commissions on Binance, for example I earn about 100$ on pair for a week and give 90$ in commissions back to Binance or even 110$, which makes it very difficult to work. (Overall I’m in small profit, only because friend gave me his referral)

Unfortunately I don’t have enough capital/money to buy enough BNB and become vip1/vip2 with commission discounts. (For vip1 you need : 50 BNB (20k usd).

Can anyone help with getting referral code of 40% kickback? Or advice something?

To add: I already have 20% ref and use bnb.
