Exchanging Coins Again Today

Thanks to a recent abundance of Time Quests + Hidden Quests and the Festival Gem Party, I've been exchanging gems daily as they're nearing the limit. I exchanged them as soon as the date changed today. Yesterday, I miscalculated my current coin balance after seeing how many I exchanged. I mistakenly thought I had 6650 when I actually had 6220 today. Now I only need 9780 more to reach the 30,000 won Naver Pay limit. That's for the 16,000 won tier. Even if I exchange up to next month's limit, I probably won't make it unless I get a big win. But then again, I don't really track or hoard them like that haha.
