So,someone help me understand this POS thing. 1%/year means that if I have 100 coins in my wallet today,after a year there will be 101 coins,right?
pretty much, but you have to leave them in the wallet.
So,the ideal thing to do is stack these coins to the sky and leave them there without touching them for a year? Also,is the staking done at once a year or is it a continuous process throughout? If continuous,what's the time interval for which they get staked?
Depending on how much you and the coin age you have a chance to have your coins staked. Then it takes 8 hours for them to return back to you. You make small percentages by doing this and consume no additional energy like mining does.
