That's what happens when coins stake. The split it roughly 2 equal parts.

Proof of stake is based off of coinage. All inputs require 30 days of inactivity to be eligible for Proof of sake minting. They become eligible at 30 days and become more likely to mint a block everyday up to 90 days when their stake weight wont grow any further

You can keep your wallet closed until the 30 day mark and it shouldnt need to be open more than a day or 2 to mint your Proof of stake blocks. When a block is minted the inputs used will be moved to the Stake column in the overview page where they will remain until the block is confirmed ( 25 Network blocks). At this point you will see a newly minted block in your transaction list for 10% of the total input which is your reward for securing the network

Do we need to keep wallet open for PoS ?

That's how pooled mining works.  You are only paid for the amount of shares your miners worked on per block.  You do not get the full amount of the block.  Even if your miners happen to find the block you still only receive a portion of it. 

oke... nice... didnt know that... thnx...
