Block reward structure : 85%MN 10%POS 5%Treasury and staking maturity is 1 hour (quite well)
By the way, POS rewards will depend on howmany coins in the hand while trying to stake your coins and it also depend on block weight. Proof-of-stake mining is similar to Proof-of-work at a technical level. but the difficult of this lottery is weighted depending on how many coins you are staking. and also howmany coins at the block weight. You should try to stake 1K coins by urself too get exact answer.
And if the balance of the wallet is less than 1000 coins, is it worth trying to get a reward? Or the odds are slim? I would like to hear an objective answer.
