If your wallet is encrypted and unlocked for staking you should be fine. Remember you are competing with everyone else who is staking. The more coins you have the better your chances.
About one million. I read here that 10k blocks were best suited for staking, so i went with that.
difficulty is much higher now try 25k blocks
Sorry if i'm asking, but do you use 25k blocks? how many stakes do you average daily? cause i'm not finding anyone giving info, though everyone seems to be staking good but me. Had tried a range of 63k blocks , 28k blocks before these, but didn't get immediate results aswell. Btw i staked twice today, but they went orphan. Lol.
