Can anybody please explain me, why did I receive POS coins for only about a half of my coins. I have all the coins in the wallet for same amount of time and they were all sent to my wallet with a single transaction. I assume that I am soon going to receive the POS for the other coins soon but I am just curious why this happened.

Thanks

"POS mining" process is just about holding coins and leaving your computer on. Only matured coins (coins stored in a wallet over 24 hours) are eligible for POS. Each block (every 45 seconds), a random lucky coin is selected to be the next "miner". If a node with the selected coin wallet is running, it will collect the transactions, make a block, and send it to the rest of the network and collect the fees. If the computer is turned off, however, then the entire network will have to select a different coin to make the transaction. This time, the unresponsive wallet will be ignored.
