strange, for 200 coins in my wallet I got only 2.6 coins from yesterday's PoS
this is kinda small if I see the screenies from other mates here
why is it so?
Let me help you with math.
POS 500 % annual = 1.36 % per day
200 coin x 1.36 % = 2.72
So, nothing strange, all work properly

thanks for help

then how can you explain the screens where people got 12-15 coins from aprox same amount like 190-200+ coins?
really odd? don't you think so?
First, you not new to POS right ?
We can't count exactly everyday you will have the same reward amount. POS is random, and a little bit luck.
If for example, your wallet running full annualy, you will exactly get 500 %. But since this only 3 days period, we can't count exactly you will get exact %.
If people got 12-15 coins by staking 200 coins, maybe they lucky and there is a little bug in POS diff retargeting, and dev already fixed, and will fork at block 12000.
But honestly i doubt people will get that much again in the future, i'm staking 5k, only got 42 coins in 18 hours.
