how to get YT SUBS and IG followers

I mean this goes without saying, but just posting good content. But I think there are sites where you can buy that sort of thing. Shouldn't be hard to find a few.

U can pay for them, but it's more funnier getting the fame by urself

You can always buy followers or subscribers. If you're interested in doing that I can help you out, just let me know.
Seeing as though they are paid followers they may not be of the highest quality, but it's still possible.

You can buy followers from various websites all over the internet, if you're not bothered they are bots.

On Youtube it can be quite hard.
1. It needs to be unique.
2. Good quality (In terms of audio and video).
3. Regular uploads.
4. Proper marketing

And the most important
5. Luck

Because in the end, its mostly about luck to get higher up.

Make little sweepstakes. Upload funny videos. The rest will come in a simple way. Just do what I say.

U should go for shoutouts for other big account or look around for forum that has bot to do that for u

You need something unique or at least something that defines your channel. Something you like. Also you should upload videos constantly, maybe once or twice a week but make sure you got your regular upload times. I think the fact that you should put effort into your videos to rise the quality speaks for itself. And yeah...just be patient. Do something that other people and you enjoy I guess.
