As much annoying as it could sound, producer/dj nowadays also has to be manager, visual artist, blogger and tons of other professions

(at least in the beginning)
If you feel like your music can attract people, you should encourage yourself and start to learn a bit of a marketing - there are tons of youtube videos (balancing with quality) about "selling yourself" as an artist, this should at least give you some basic understanding.
More than that it's just about opening the doors that nobody openned before you = you need to find unique way of how to get heard, not only sitting on soundcloud. This path is full of tries and fails and YOU need to discover one path that suits you best.
Few examples of original breakthrough:
myspace.com - Justice, Skrillex (closed door nowadays

)
showing unique content on youtube - Madeon (Pop Culture made him widely known)
Reddit - (I think) was a place that helped KRNE
Create unique-style remixes - Kygo
Or just put a mask on and create this "mysterious artist" persona
As you can see, nobody followed one formula how to reach so many people, they had to open unused "doors" to success
