Spread your balances across several different addresses.  So if you have 1000 coins put 100 coins into ten different addresses and leave the wallet open and you won't be disappointed.   You'll get stake for each address about once per day. If you close your wallet for a few days when you open it you will get more for the days you missed.  It trickles in but it adds up pretty quick if you don't move the coins especially if you leave your wallet open.  If you have 1000 coins you can get one coin every 7 days or so which is better than a sharp stick in the eye,  1500 coins you can get 1 btcd every four days or so and with 2000 you will get a coin every couple of days.  That rate may change in the future.  I don't know.
