Newbie question about Proof of Stake

[HashFace]

So, I have been doing some reading and watched some you tube videos, but I'm still not clear on how proof of stake really works.  Am I to understand that if you hold your coins in a wallet, you simply get more coins?  Like a dividend?  That raises a few questions for me.

1)  Do most PoS coins have minimum you must stake to get payouts?
2)  Are the payments made often, like once a day, once a week?
3)  Are the payments simply divided proportionally amoung stake holders, or is there some luck or preferred treatment involved?
4)  Where do the payment coins come from?  Are they just newly minted coins, like a block reward, or coins the developer held back?
5)  Do the stake payment eventually end?
6)  What percentage increase in your holdings do you generally see? 

I know a lot of this depends on the specific of each coin, but is are there general answers to those questions?  I'm most interested in how etherium will work after the POS switch, if anyone has any insight or opinions on that.

I can't speak for all PoS coins but with Spectre coin:
1. You need some sort of balance over zero and stake for at least 8 hours. The more you stake will get you paid more often. E.g. 100 coins would pay out roughly 1 a month where as 1500 coin would pay twice a week. Daily payments start at around 5000 coins.
2. Payment time depends on the maturity of your coin. Maturity comes from staking it for so long. The higher your maturity, the more likely your coins will sign the new block and receive the reward. More coins give you more levels of maturity.
3/4. With xspec, the payment comes from newly minted coins, equal to 5% of the total supply annually. This 5% is divided amongst those who staked based on maturity and the amount staked, which can give you much over 5% of your stake because not everyone stakes their coins, even tho they still count towards the total supply. You cannot receive less than 5%.

5. No, staking is a means of account for some of the inflation, it does not end. At least with xspec.
6. 5%+ annually. Your daily reward can vary greatly, best to take a average over a long period of time.

Again these answers are just for xspec, but hopefully it gives you somewhat of an idea of how/what PoS is.

Thanks for that detailed answer.  I really appreciate it.

I can't speak for all PoS coin as I'm not an expert, but e.g. BLOCK dividend is newly minted coins from blocks.

That means there is an element of randomness to the staking, and all returns are on average.

I've seen returns on PoS coins usually ranging in 3-7 % annually. But it could depend on many factors, e.g. how many coins that are actually staking. If a lot of people keep their coins on Bittrex e.g. they aren't staked, and the return for those that are increase.
