I have a problem with PoS.
I sent HBC to offline wallet on 8 Dec and I was staking on 13 Dec, received HBC that I mined.
But When i restart my laptop, It said "Not staking because you don't have mature coins" again like 3 days ago.
What should i do brO? 
How many coins do you have in your offline wallet. Because the more people start staking the less you get staking results or coins out of it. So it can take 5 days until you stak again so wait two more days and if it still the same come back to us please and we help you.
I have 375 HBC in my offline wallet on 12:57 PM (GMT +7) 8 Dec and I received 7.7 HBC for the first time mine on 20:20 PM (GMT +7) 14 Dec.
I think it's correct if i have to wait 5 days to stak again. I will receive 10% a month.
Which I turn off or turn on the offline wallet until I can staking again.
Thanks for you reply.
In HBC I trust <3
