My wallet has been unlocked all day.
During the day it said my stake was only the coins I had bought off an exchange, not the ones I mined and now there are all 000 next to stake.
How does the stake work in PoS?
Make sure to not close your wallet, lock it or turn off your pc. Everytime you do, you have to unlock it and restart the staking. I think the minimum stake time is 24 hours (someone correct me if I'm wrong), so if you leave your wallet open all day and overnight you should see some stake rewards in the morning.
