Question about Continuous payment and crysta

[Quedari]

So for example, let's say I buy $30 worth of Crysta (3,000 Crysta) via UltimatePay, with $14.95 on my account. After the 3,000 Crysta is paid for on the day make my second billing, I'll be left with 10 Crysta from the $29.90 I have paid. Will my account be automatically cancelled the moment I have 10 Crysta or will I have a grace period before the day I am billed again to buy more Crysta?

Starting balance: 3000. First month billed: 3000-1495=1505. 30 days later, second month billed: 1505-1495= 10. 30 days later, the third month will be billed. At some point during those 30 days, you'd need to put more crysta in your account, or when SE attempts to bill the third month, you'll get canceled until you put more in. Until/unless SE gives us the option to have recurring payments with crysta, I just made a reminder on my phone's calendar to buy more crysta before the next billing time.

So, yes, I'll be able to buy more crysta for the third month before the third month is billed?
