Algorithm of PoS in the wallet is strange. Ok, I transferred coins with many confirmations into another address, it showed expected time to earn reward is 21 hours, then changed to 23 hours, then 1 day, then suddenly one piece finally staked, now again showing expected time to stake is 1 day. At least it began to work now
POS have lot luck involved
and the values displayed are time based on statistics based on the actual POS difficulty
just ignore that timer
the more coins u have in good coin pile size the more often u find a block
its that easy
there is no progress bar in staking
every new block choose a random winner
same as in rolette the chance that next one is black is 50% each time
it dont increase just because the last 3 times was red
still statistic show on average black and red are both at ~50%
