how does the staking work?
I got my POS Reward on 27 January 2018. On my wallet, expected time to earn reward vary between 2-4 days.
But till today, 1 February 2018 (5 days). it is no POS reward yet. what happened?
It is totally random. You can get 2 times a day, or wait for 5 days, depends on luck. I have ~1 day estimated, but 4 days nothing. It can happen.
Random... correct me if I am wrong, you hold POS coin (staking), expecting to get POS reward. But, if you said it's random, It's not good to invest this coin for staking.
More coins you have - more chances to get PoS reward. Time in your wallet shows *average* (not exact) time to get reward. That is what I mean by word "random".
