Based from my experience.

I have cashback & Total Deposit Bonus from my rank on BK8 (Silver VIP). Maximum Cashback 750,000 IDR (47$) with 3x waggering and Total Deposit Bonus Maximum 1,500,000 IDR (around 100$) with 10-15x wagering. With that number, still I can't finish these, don't forget I can withdraw any amount I can win without getting limit.

Meanwhile 200x wagering + maximum 20$ win + KYC. I guess is not worth from the wagering, time we are spending, amount we are win and we still need to send KYC.
