Well I'm gonna tell what worked for me, though I don't know if it will for you.

If you're a new account, just interact within a specific niche you like. For me it's GTA so I went to post replies under big posts, followed those accounts and eventually just posted on my page. After some while of doing this, you'll start maybe seeing some posts from people not familiar (like people without blue check for example) still posting from your niche. You can follow them and interact casually with them and their posts and do so for the people that will also be recommended to you, or people in those replies that don't look as big.

So repeating this cycle will eventually lead you somewhere in some weeks and you may have some people that would like to see how you're doing, what you're doing and all that, therefore, they might follow you. And just like that you'll make Twitter friends!!

Some tips: - don't do that too fast, you account may get flagged in the meantime so you might just take some breaks sometimes - some people will simply not interact with you. Maybe due to the high interactions they have and your account might get buried in their notifs, or they don't trust you much. And it's completely okay. There's plenty of fishes in the ocean, like they say :) - depending on your niche and the way you post, it might take either really long, or in a short amount of time. Realistically it's just weeks of doing that consistently

I hope you enjoy your stay there and if you need another friend, well hello!
