Is it possible to go viral without paying for promote

Yes but your content must be relevant... That is, it must retain and attract people

Yes!!!!

I went viral multiple times. I don’t pay for promotion at all. I only have 2,115 followers. I do nursing content.

There are multiple ways to go viral! You should be asking yourself why you want to go viral and what you'd do immediately afterwards though. Without a proper game-plan and complete goal, some folks go viral and go back to their regularly scheduled and viewed content very soon after.

Organic virality is always WAY better than a paid approach.

Yes… people do it all the time

Yes

Yeah, but I feel like once you pay tiktok won't boost your videos unless you pay again. I have no experience. Just things I've read 🤷
