What do i need to do wallet has been open for more than a week and hasn't staked yet .My balance is 1831.
Thank you for any help
It may take more than one week to get first stake for that amount, also make sure it is unlocked.
Check config.dat for:
"mining":{"proof-of-stake":"1"}
and debug.log for string:
[INFO] - coin::mining_manager::pos_tick: Mining manager, mining (pos) with 1 transactions in block, bytes = 181.
If you see it as above, then everything is fine and all you need, to wait more.
