POS question

[EMIF]

Hi,

There are lots of POS coin. But I want to learn how the rate works?

For example ;

Lets say we have 100m pos coins available atm. And the rate per year is 5 %. And then , we have 50m coins which never reaches to minimum stake age for 1 year.
So , question is this: How many coins will be staked for this coin in 1 year?
i.e. , 100m*5% = 5m or 50m*5=2.5m

It compounds.. so as you're getting stake / interest,  you start earning stake on that interest received.

Thanks for the reply, but that is not exactly what I ask. I want to learn how 5% stake rate applies to all coins or to only staking coins.

In above example , half of the coins will never reach to minimum stake age because of movement of them. So , they never stake (assuming continuous movement of these coins).
 
Then what is the number of stake coins approximately in 1 year?

2.5 m or 5m ?

If it is 2.5m then the inflation rate of this pos coin will be app. 2.5 %.
If it is 5m then the rate for staking coins will be 10% .

So , which one is valid?

Under your scenario, 2.5m.
Minting of PoS blocks is based on coin age.
Ergo, unstaked coins will not qualify for minting as they will not have any coin age to be consumed.
