What are the quota rules for opening sub recharge agents?

Dear user, the quota for opening sub recharge agencies depends on the amount of diamond sales during the previous month: over 2,000 = 3 agencies; over 4,000 = 4 agencies; over 5,000 = 5 agencies; over 6,000 = 6 agencies; over 7,000 = 7 agencies; over 8,000 = 8 agencies; over 9,000 = 9 agencies; over 10,000 = 10 agencies; over 20,000 = 15 agencies; over 30,000 = 20 agencies. The quota is recalculated on the 1st day of every month. If your current number of sub agents exceeds the newly available quota, the system will close the excess ones according to the order they were added, starting with the most recently added sub recharge agents.
