Pos 3.0 brings incitement for people to operate online nodes and be active in the staking process.

before 3.0: The best strategy was then to keep your node offline and then only bring it online rarely to get a huge stake payout. People with not many coins got a small stakes while people with lots of coins got large stakes.

after 3.0: You need to run an always online node if you want to get your 1% interest. People with not so many coins will get a much higher stake reward relative to people who have a lot of coins. If you have a lot of coins and stake all the time you will be granted your 1% interest. If you have a lot of coins and do not stake you will be granted 0% interest. If you have not that many coins and stake all the time you will be granted more than 1% especially in situations when not all issued coins participate in the stake process.
