Honestly, even if an EP doesn't sell it's nice to have versions of it up so that you leave a small digital footprint. I produced a couple of albums that are lost to time because they happened before Bandcamp but at least I've established a library for people to get lost inside. An album can make a sale a year down the road, you never know. Think of this album as a footprint :3
Don't get too caught up on the idea of money. Giving people an opportunity to pay you is important but always produce because you love doing it!
