How do you share beats without risking people stealing them?

I’m a new producer and I’ve been working on making beats. It’s going really well so far and I can tell my musical background is helping me. I’ve been in bands before, including a metal band, and we would write, record, and release music together. But I’ve never really played shows or had to put myself out there, so this is totally new for me. I’m starting from the bottom with zero connections, and I’ll admit I’m nervous and feel out of place, but something is calling me to do this and I feel ready.

My main goal right now isn’t to get paid. I just want to make music for the love of it. That said, even if I’m not earning money yet, I don’t want people taking credit for something I put my passion and hard work into. I don’t really understand how I’m supposed to get myself out there and have people hear my beats without running the risk of them taking my work and claiming it as their own. I don’t want to just post a Dropbox link or put all my beats on Instagram because people could easily steal them. I’m in a totally different genre than I’m used to, I don’t know how to network, and I could really use some advice.

How do other producers handle this while still getting exposure and sharing their work?
