Answer:
Honestly, the way to get collabs is posting your music everywhere. Anywhere with a large amount of viewers active on it would be great for you. Through all of it, remember that every single star rapper was in your exact place. They grinded their way up to the top and you have to do the same. I wish you the best of luck. When I see you on the top one day, I'll be proud, not goona lie.
Explanation:
I have a YT with about 215 subscribers (I know it's not much), but what's your rapper name so I can shout you out? Also, if you want I can use your raps as backround music for my videos (I do edits.)
It's completely up to you.
