Do you pause a telegram ad campaign after it become profitable?

HI,
I am working on telegram ads and noticed let say a campaign is performing well, subscriber costs are acceptable, and the numbers look profitable. Do you keep it running as long as possible, or do you pause it before performance start to decline?
Love to hear your experience

I generally don't pause a profitable campaign just because it 's profitable. If the economics still make sense, I would rather keep it running and monitor the trend closely.

What I have found is that most telegram campaigns don't fail overnight. Performance declines gradually as the audience becomes saturated. When I start seeing subscriber costs rise consistently or engagement quality drop, that's when I begin testing fresh creatives or new channel groups

If the campaign is still delivering Quality subscriber at a good cost, I usually let it run and monitor it closely. If I talk about my work experience on telegram ads I don't pause a telegram ad campaign just because it becomes profitable.

If I notice subscriber costs staring to rise or engagement dropping , I will either reduce the budget ,refresh the creative or test new channels rather than stopping it immediately.
