I feel like everything Hive related has been a money pit for me. Splinterlands has been quite a bad one as well. I was making a decent return renting cards at one point, but suddenly that stopped and the value of all my cards keep going doing down. On top of that, I have exponentially more SPS than I started with, but my entire holdings is worth less than the initial value of the small amount that I started with.
I've tried to stay optimistic with this ecosystem, but it gets harder each bull run watching nothing happen over and over again.
