Update: After I received some part of instructions. I decided to open scam report. Even though it's not clear yet that it's legit or not but I pretty sure it's considered as scam.
Reason
1. His first instructions is to register bustabit then deposit. I pretty sure that It's related to bustabit script at this point.
2. After 1 hour of his last response (11 hours ago). I asked him is it bustabit script? He didn't answer me since then.
3. There is no way you can make guaranteed profit via Bustabit. Therefore, I'll mark this as scam since he said it'll make at least $20 per day.
I will make scam report soon.
