I'm very confused about the SAT2 staking feature. It was my understanding that coins which stay in the wallet, earn interest over time. For a few days now, I have been receiving micro transactions ... about 0.01 - 0.02 SAT2 every 15 minutes or so. The thing is, my balance is actually going down. When I woke this morning, my balance was 13959 SAT2, as of now, it's been reduced to 13956 SAT2. Can anyone elaborate on this?
