Is your wallet unlocked?
Yes, it is and has been unlocked.
In that case, I would imagine that it have to do with the total amount of coins and their stake weight...though I would think that a week is a bit long to have to wait.
They will stake though...
There's nothing else you need to do. A week isn't long at all. If you only have 1000 coins, it could take over a month to stake.
Ok, thanks.
I was mining them and sending them to the exchange originally, but then read about the PoS, so started routing them to my wallet. I thought I had read it would stake around 3 days, that is why I was becoming concerned. Does the amount of coins you have in your wallet affect it as well?
Yes. Number of coins, number of inputs, length of time coins have been in that address, and amount of time you leave your wallet open; all will affect how often you stake.
