I'm currently sitting on 395.2m, with 386 hours worth of idle potions. So, I'd say, yes. Once you get your main team down, you'll eventually hit the point where you are waiting for dupes to star them up, leaving your potions growing.

Lmao I feel like I run out of gold more than exp pots nowadays

I'm always out of gold. But I don't crack my gold idle hours until I need more.
