I have almost the same negative results (paying monthly for more then half a year) running ~news but I see it as a long distance marathon and keep up on paying my rent and enjoying informing SN users about the most important (in my opinion) news and events worldwide, hoping it will eventually reward me in future. 😉
So my advice to you is to buckle up, try to post quality content (in your case answers, tutorials about SN as a platform), lower your expectations about your territory revenue and don't let the negative Sats balance give you up!
Wish you luck 🤞🍀 buddy!
