Stake reward goes all from 1 to 3 mil linda. That is why rewards are random.
I can agree with the fact reward goes from 1 to 3 mil, but you are either illogical person, or you did not read. On the same day the reward has to be constant across all stakeholders. Actually reward is constant. Meaning: On the same day the % of reward across owners has to be the same. That is not the case now. It is fully random.
It's not possible to have earn stakes for 1mil coins and not earn anything for 4mil coins on the same day.
Staking for this coin is either fake, buggy or random. I'm too lazy to read their code, but I owned CoinonatX by the same developers and it was the buggiest software I have seen in my lifetime.
If you want more pay outs , get more coins or invest into a MN, you will get several pay outs per day.
