I am still a little bit confused about that staking...

How often should i open my wallet for best profit:
1. Once / week
2. Once / day
3. Keep it open 24 / 7
4. Other
Thanks in advance.
You won't need to open your wallet, it will stake as long as your address has balance in the network.
dev,
I think you are wrong , I didn't get any stake when my wallet is closed.
guys,
How about you?seems i have to keep it open 24/7 if i want to earn the stake.
My wallet likes to stake itself at night. I don't have internet at home except when I use my phone as a Hotspot. In the daytime i'm at work and the comp at home is off. Once I get home from work. I turn my hotspot on and my comp. I let my Sharecoin, Black and Energy wallets sync..All done. Sooner or later the network catches up with your address and sends you the stash. Good Luck to ya
