OP asked how POS works.
Can we agree that PoS has more positive things than flaws (like inflation, on which Daedelus is avid supporter )?
You haven't been reading the posts in this thread. Troopnetpt and I are against inflation, you are the only one in favour.
It would help if you stopped trying to distort others views and just present your own.
I am in favor of inflation because if you have higher inflation then people will pull their Coins off the exchanges in order to Stake them which reduces the amount of sell orders on the exchange and increases the security of the network. When you have higher inflation (the sweet spot), there is enough liquidity that you have high volume on the exchange and people can trade on the exchanges and make profits of buying and selling but if bought it a little high, then can hold on to them and Stake and still gain profit later on. A lot of buying and selling (volume) creates distribution and over time it distributes the Coin more evenly provided there is also a good amount of development work happening. Very few people are going to buy and hold on to any Coin forever, especially if they are building a good amount of Coins and the price is rising, if you bought 1 btc worth and now it's worth 10 btc then you would probably sell some to make ROI.
