How to stake coins?
1) First you need a balance, to stake.
2) Leave your wallet open, don't spend your coins.
3) You can reserve certain amount of coins to stake, under "settings > options" in wallet GUI
4) Coins start staking after holding for 8 hours. Passively.
Still not sure about point 3.
In my wallet under setting->options If have an option "Reserved amount does not participate in staking and is therefore spendable at any time" It contradicts point 3
I have recived some staking rewards, but not sure I was rewarded when I left it to zero or when i filled in entire 5500.
Also "Stake:" amount in wallet is empty in both ways, its all in "Spendable:"
