volume 16k4 should be 20u fee/day, 15 days is 300u, still enjoying kkk

Calculating that 1 account if holding 10k and grinding a volume of 16k2 earns 18d each day. 15 days is equivalent to 270d, considering the mechanism where each deal deducts 15d. Taking an average of 190-200d, then 1 account can take around 4-6 deals in 15 days, and around 8-10 deals in a month. On average, 1 deal is about 100u, so 1 account can also earn 800-1000u, equivalent to 20 to 26 million VND. Quite good, right? We can manage with 3 accounts to get by.
