The staking confuses me, though to be far I don't have much experience with staking coins in general.  I've been running my wallet for about 12hrs a day when I'm online, the same 12 hrs each day, the first week I was getting coins every other day without fail and now for the past week I haven't received any.  It just says expected time to reward 2 days or 3 days or 1 day.  I'm assuming I'm just missing the time when they're being distributed?  So the staking rewards happen at random times and you have to leave it on 24/7?
