When you say "proof-of-stake, minting, coins are generated without mining based on the amount that you have in your wallet" you mean that i will have some extra coins added into my wallet without doing nothing at all, just for keeping the coins for at least 20 days?

In wiki i read "Proof-of-stake is a method of securing a cryptocurrency network through requesting users to show ownership of a certain amount of currency."

Sorry for my stupid questions but i cannot find someone to explain this to me.
