I'm staking force from my wallet i got 750 force and it stop staking saying i have no mature coins is that right do i have to wait anther 24 hours to stake agen?
Yes after a reward staking, the coinss become immature for 24 hours. They are put back into play 24 hours after your rewards.
I also stakes, it is interesting to divide your balance into several packages of 5000 Coins through the control option Coins. Thus you will win after 24 hours 1 reward per lot of Coins.
